Verify Proper Inlet Pressure
Verify Proper Inlet Pressure
Before starting up the unit, smell all around the heater for gas. Be sure to smell next to the floor as some
gas is heavier than air and will settle on the floor.
When turning the gas shut off valve, only use your hand. Never use tools to turn the knobs as it may
damage the valve resulting in a fire or explosion. If the knob is stuck, do not try to repair it; contact a
qualified service technician or your local gas company.
To verify the proper inlet pressures, follow the following steps:
1
Turn off the gas supply at the manual gas shut off valve and remove the plastic top panel.
2
Remove the inlet pressure tap plug on the gas control valve.
3
Connect a pressure gauge, tube, and manometer.

Turn on the gas supply at the manual gas shut off valve.
5
Turn on the electrical power to the heater.

To light the burner, set the room thermostat to a point above room temperature.
NOTE:
This heater is equipped with an ignition device which automatically lights the burner. This
heater cannot be lighted manually. Do not try to light the burner by hand.
Verify
minimum
inlet gas supply pressure:
7
Turn on all other gas appliances that are on the same supply line. If the other gas appliances have
multiple inputs, set it to the maximum rating.
8
Observe the pressure rating on the pressure gauge.
The minimum inlet gas supply pressure for:
• Natural gas is 5.0 inches W.C.
• Propane gas is 11.0 inches W.C.
Verify
maximum
inlet gas supply pressure:
9
Turn off all other gas appliances on the same supply line.
10
Observe the pressure reading on the pressure gauge.
The maximum inlet gas supply pressure for:
• Natural gas and propane gas is 14.0 inches W.C.
IMPORTANT:
If the inlet gas supply pressure is not within the minimum and maximum range as
shown on the rating plate, contact your gas supplier.
Removing pressure gauge from inlet port on gas valve:
Set thermostat or other control device to the lowest set point.
11
After heater has completed the post-purge cycle, turn off the electrical power to the heater.
