NOTE: If the appliance does not operate, follow the instructions "To Turn Off Gas to Appliance" printed below (and on the Operating Label on the heater) and call your service technician.

10.Thermostat calls for heat, energizing the venter motor(s).

11.The main combustion air pressure switch (Sizes 800 and 1200) and each heat section pressure switch close, firing the heater.

12.Burner flame is sensed and in 30 seconds after the gas valve is energized, the fan motor(s) is energized.

13.If the flame is extinguished during the main burner operation, the integrated control system closes the main valve and must be reset by interrupting power to the control circuit. (See lighting instructions on the heater.).

TO TURN OFF GAS TO THE APPLIANCE

1)Set thermostat to lowest setting

2)If service is to be performed, turn off all electric power to the appliance.

3)Open the access door(s).

4)Turn the gas control knob(s) clockwise to "OFF". Do not force.

5)Close the access door(s).

Check installation after startup:

Place the "Owner's Envelope" containing the Limited Warranty, this booklet, and any control or optional information in an accessible location near the heater. Follow the instructions on the envelope.

Vent System Testing Procedure

1.Seal any unused openings in the venting system.

2.Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1 or CSA B149.1 and B149.2, Installation Code for Gas Burning Appliances and Equipment, and this manual. Determine that there is no blockage or restriction, leakage, corrosion or other deficiencies that could cause an unsafe condition.

3.In so far as practical, close all building doors and windows and all doors between the space where the heater is and other spaces of the building. Turn on exhaust fans so they shall operate at maximum speed. Do not operate a summer exhaust fan.

4.Light the heater following the lighting instructions. Adjust the thermostat for continued operation. Verify that combustion products are venting properly. After determining that the heater vents properly, return doors, windows, and exhaust fans to their previous conditions. If improper venting is observed, the venting system must be corrected.

With the heater in operation, measure valve outlet gas pressure. If operated at high altitude, adjust outlet gas pressure for altitude. See information and instruc- tions in Paragraph 12.

Using the thermostat, turn the heater off and on, pausing two minutes between each cycle. Observe for smooth ignition.

DANGER: The gas burner in this gas-fired equipment is designed and equipped to provide safe controlled complete combustion. However, if the installation does not permit the burner to receive the proper supply of combustion air, complete combustion may not occur. The result is incomplete combustion which produces carbon monoxide, a poisonous gas that can cause death. Safe operation of indirect-fired gas burning equipment requires a properly operating vent system that vents all flue products to the outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT IN A HEALTH HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR DEATH.

Always comply with the combustion air requirements in the installation codes and in Paragraph 9. Combustion air at the burner should be regulated only by manufacturer-provided equipment. NEVER RESTRICT OR OTHERWISE ALTER THE SUPPLY OF COMBUSTION AIR TO ANY HEATER. Heaters installed in a confined space must be supplied with air for combustion as required by Code and in Paragraph 9 of this heater installation manual. MAINTAIN THE VENT SYSTEM IN STRUCTURALLY SOUND AND PROPER OPERATING CONDITION.
