7 Installation of V enting for Outdoor Units W ARNING Do not install units in locations where flue pr oducts can be drawn into adjacent building openings such as windows, fresh air intakes, etc. Distance fr om vent terminal to adjacent public walkways, adjacent buildings, operable windows, and building openings shall conform with the local codes.
8 W ARNING The following guidelines must be followed for all indoor units: 1. Installation of venting must conform with local building codes. In the absence of local codes, installation must conform with the National Fuel Gas Code, ANSI Z223.1 or in Canada, CAN/ CGA-B149 installations codes.
9 Installation of Standar d Indoor V enting Standard Indoor V enting uses one penetration through an exterior wall or roof for venting the flue exhaust. The combustion air is supplied from the air inside the building. Units must not be installed in a potentially explosive, flammable, or corrosive atmospher e.
10 NOTE V ent piping is supplied by others and not supplied by manufacturer . Installation of Concentric V enting (General) Concentric venting allows the exhaust pipe and combustion air pipe to pass through a single hole in the roof or wall of the building.
11 Concentric V enting – V ertical Refer to the diagram below for venting on vertical concentric systems. Maintain at least 12 inches between the top of the combustion air inlet terminals and the bottom of the exhaust terminal.
12 4. Install Combustion Air Pipe Attach a field-supplied combustion air pipe to the concentric side of the CV A. Be sure to pr ovide enough combustion air piping to pass through the r oof and provide the minimum clearance of 12 inches between the combustion air intake and the exterior surface of the roof.
13 2. Install Combustion Air Pipe Run a combustion air pipe from the unit’ s combustion air intake through the exterior wall to the outdoors. The combustion air pipe must terminate at least 12 inches from the combustion vent pipe and 24 inches from the exterior surface of the outside wall.
14 1. Install Exhaust Pipe Run an exhaust pipe from the unit’ s combustion exhaust through the r oof to the outdoors. The exhaust pipe must terminate at least 12 inches above the outside surface of the roof. This clearance may need to be increased to accommodate snow accumulation.
15 Installation - Electrical Wiring IMPORT ANT Before connecting power to the unit, r ead and understand the following instructions and wiring diagrams.
16 NOTE Large evaporative coolers may requir e a separate power supply . 6. Wir e the Evaporative Cooler (optional) Reference the ladder diagram on the inside of the control center door for corr ect wiring of the pump and the optional water valves. 7.
17 Installation of Gas Piping IMPORT ANT All gas piping must be installed in accordance with the latest edition of the National Fuel Gas Code ANSI/Z223.
18 Installation - Evaporative Cooler Piping (optional) Evaporative Cooling with Auto Drain and Fill Auto Drain & Fill Evaporative Piping 1. Install the W ater Supply Line Supply line opening requir ements vary by unit size and arrangement and are field-supplied.
19 NOTE The following instructions are pr ovided for evaporative coolers equipped with the W ater Wizard™ only . Additional instructions are pr ovided for evaporative coolers equipped with the auto drain and fill or bleed-off. W ARNING Disconnect and lock-out all power and gas before performing any maintenance or service to the unit.
20 Installation - Dir ect Expansion (DX) Coil Piping (optional) 3. Wir e the Solenoid(s) Wire the supply line solenoid and drain solenoid as shown on the unit’ s wiring diagram in the control center . 4. Wir e the T emperature Sensor If the evaporative cooler shipped separate from the unit, the temperature sensor must be wir ed.
21 NOTE If a hot gas bypass kit was provided by others, r efer to the manufacturer’ s instructions. NOTE Failure to obtain a high vacuum indicates a gr eat deal of moisture or a small leak. Br eak the vacuum with a charge of dry nitrogen or other suitable gas and recheck for leaks.
22 1. V erify Coil Hand Designation Check the coil hand designation to ensure that it matches the system. Coils are generally plumbed with the supply connection located on the bottom of the leaving air -side of the coil and the return connection at the top of the entering air -side of the coil.
23 Start-Up - Blower Refer to the Start-Up Checklist in the Reference Section Before Pr oceeding Further! Pre Start-Up Check Rotate the fan wheel by hand and make sure no parts are rubbing. Check the V -belt drive for proper alignment and tension (a guide for proper belt tension and alignment is provided in the Belt Maintenance section).
24 6. Set-up Optional Components Adjust the settings on the optional components. See the Control Center Layout in the Refer ence section for location of optional components.
25 Start-Up - Furnaces (all units) IMPORT ANT For the unit to function properly , all stage or modulation valves must be set for high and low fire. NOTE There ar e five furnace control options available. Be sure to r efer to the specific instructions for your control type.
26 Start-Up - 2:1 Staged Contr ol 1. Send Unit to High Fir e Send the unit to high fire by setting the temperature selector to its maximum setting. 2. Check the High Fir e Manifold Pressur e Using a manometer , measure the burner manifold pressur e at the manifold pressur e test port.
27 W ARNING Once the high and low fire have been set, be sur e the press the Function key to end high fir e mode. The middle LED light, L2, will stop flashing when high fire mode is of f. NOTE Step 5-7 are for adjusting the discharge air setting. The discharge air temperature setting is factory set to the recommended 70ºF .
28 NOTE The room override function r equires a field-supplied thermostat to be installed in the space and to be wired between terminal 31 and 32 in the unit’ s control center . Reference the unit ladder diagram. 11. Edit the Setting Use the Up or Down key to change the room override setting.
29 Start-Up - 2:1 Electr onic Modulation 1. Send Unit to High Fir e T ur n the temperature selector to its maximum setting to send the unit to high fire. 2. Check the High Fir e Manifold Pressur e With the unit at high fire, use a manometer to measur e the burner manifold pressure at the manifold pr essure test port.
30 Start-Up - 4:1 Electr onic Modulation 2. Check the High Fir e Manifold Pressur e Before setting high fir e on the EXA valve, turn the regulator scr ew on the combination valve all the way in (increase pr essure). Using a manometer , measure the high fire manifold pressur e at the pressur e test port.
31 NOTE The following steps are for adjusting the discharge air setting. The discharge air temperature setting is factory set to the recommended 70ºF . Only adjust the setting if needed. NOTE After modifying a setting, the Enter key must be pressed to save the change.
32 3. Set the Enthalpy Changeover Set Point (optional) If using an economizer , the enthalpy changeover setting must be set. If differ ential temperature or differ ential enthalpy control is used, set the enthalpy changeover set point to D .
33 Start-Up - Evaporative Cooling (optional) Leaving Air Entering Air 45º 15º NOTE A jumper will need to be installed in the control center to power the evaporative pumps with the blower(s) off. Refer ence the unit’ s ladder diagram to determine proper terminals.
34 NOTE Steps 6 through 8 ar e provided to adjust the minimum cooling temperature. The minimum cooling is preset to the factory r ecommended 75ºF (24ºC). Only adjust if needed. NOTE The inlet air sensor function overrides and shuts down the evaporative cooler if the outside temperature falls below the minimum cooling temperature.
35 NOTE The Freeze T emperatur e is preset to the factory recommended 45ºF . Steps 9-11 should only be completed if the Freeze T emperatur e needs adjustment. NOTE The Freeze T emperatur e is the temperature at which the supply solenoid closes and the drain solenoid opens to drain the supply line, preventing possible freeze damage.
36 Building Pressur e Control — a variable frequency drive is controlled accor ding to input from a pressur e sensing device. T ur n both knobs to the upper most pressur e setting. Y ou may have to remove the outdoor pr essure tap tubing. V A V systems should go to maximum speed.
37 Building Pressur e Control - a modulating spring return actuator is used to control the r eturn air amounts. The return air damper modulates from fully open to fully closed based on a signal from a remote pr essure sensing device. T ur n both knobs to the upper most pressur e setting.
