24. Check Installation and Start-Up

Check the installation prior to start-up:

oCheck suspension. Unit must be secure and level.

oBlower Model - Check to be sure that all shipping supports have been removed. Rubber feet must be on the motor bracket bolts. See Paragraph 4.

oCheck clearances from combustibles. Requirements are shown in Paragraph 6.

oCheck vent system to be sure that it is installed according to the instructions in Paragraph 9.

oCheck piping for leaks and proper gas line pressure. Bleed gas lines of trapped air. See paragraph 10.

oCheck electrical wiring. Be sure all wire gauges are as rec- ommended. A service disconnect switch should be used. Verify that fusing or circuit breakers are adequate for the load use.

oCheck that any field-installed options have been included in the installation.

oBlower Model - Check belt tension. See Paragraph 14.

Start-Up -- Typical Operating Sequence:

1.Set thermostat at lowest setting.

2.Turn on main and pilot manual gas valves.

3.Turn on the power to the unit.

4.Set the thermostat to desired setting.

5.Thermostat calls for heat, energizing the venter motor.

6.Venter pressure switch closes, firing the unit, after pilot prov- ing sequence.

7.Fan control senses heat exchanger temperature, energizing the fan or blower motor.

8.If the flame is extinguished during the main burner opera- tion, the safety switch closes the main valve and recycles the spark gap.

On units equipped with lockout device, if the pilot is not es- tablished within 120 seconds, the unit locks out and must be reset by interrupting power to the control circuit. (See light- ing instructions on the heater.)

Check installation after start-up:

oWith the unit in operation, measure manifold gas pressure. Manifold pressure for natural gas should be 3.5" w.c. and 10" w.c. for propane gas. See Paragraph 10.

oTurn the unit off and on, pausing two minutes between each cycle. Observe for smooth ignition.

oBlower Model - Check motor amps with an amp meter. The maximum amp rating on the motor nameplate must not be exceeded.

oPlace 'Owner's Envelope" containing Limited Warranty Card, this booklet, and any optional information in an accessible location near the heater. Follow the instructions on the enve- lope.

DANGER: The gas burner in this gas-fired equipment is designed and equipped to provide safe and economically 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 which 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 Paragraphs 6 and 7. 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. Indoor units installed in a confined space must be supplied with air for combustion as required by Code and in Paragraph 7 of this heater installation manual. MAINTAIN THE VENT SYSTEM IN STRUCTURALLY SOUND AND PROPERLY OPERATING CONDITION.
