Not suitable for use with conventional venting systems. LIMIT ATIONS These units must be installed in accordance with the following national and local safety codes. 1. National Electrical Code ANSI/NFPS No. 70 or Canadian Electrical Code Part 1, C22.1 (latest editions).
Refer to Figure 5 for information concerning rear and bottom supply and return air duct openings. ROOF CURB On applications when a roof curb is used, the unit must be posi - tioned on the curb so the front of the unit is tight against the curb.
Scroll compressors operate in one direction only . If a three phase scroll compressor is experiencing: • Low amperage draw • Similar discharge and suction pressures • Increased noise level then the compressor is operating in reverse. T o correct this condition, switch any two (2) line voltage leads at the contactor .
3. Use wrought iron or steel pipe for all gas lines. Pipe dope should be applied sparingly to male threads only . CAUTION: If flexible stainless steel tubing is allowed by the authority having jurisdiction, wrought iron or steel pipe must be installed at the gas valve and extend a minimum of two (2) inches outside of the unit casing.

2. Check for correct manifold gas pressures. See “Checking Gas Input”. 3. Check the supply gas pressure. It must be within the limits shown on rating nameplate. Supply pressure should be checked with all gas appliances in the building at full fire.
3. After maintenance of the pilot assembly , always measure the resistance across the ignitor . If the resistance is greater than 10 ohms, discard the ignitor and replace it with a new ignitor .
NORMAL MAINTENANCE WARNING: Prior to any of the following maintenance proce - dures, shut off all power to the unit, to avoid per - sonal injury . Periodic maintenance consists of changing or cleaning filters. Under some conditions, the main burners should be cleaned.
Checking Supply Air CFM T o check the supply air CFM after the initial balancing has been completed: 1.Remove the two ¼ inch dot plugs in the duct panel. 2.Insert at least 8 inches of ¼ inch tubing into each of these holes for sufficient penetration into the airflow on both sides of the indoor coil.
