PREPARATION FOR START-UP
WARNING:
DO NOT TURN ON GAS AT THIS TIME
2.1
Check Power Supply
With volt meter at incoming power check voltage between:
Hot - Common
(
~
120 VAC)
Hot - Ground
(
~
120 VAC)
Common - Ground
(< 1 VAC)
If Common - Ground is > 1 VAC -
STOP:
Contact electrician to correct ground failure. Warning: Failure to do this may
burn out 120V-24V transformer, or may cause other safety control damage or failure.
2.2 Attach Manometers to Measure Pressures
•
Attach 24" scale manometer to the first main gas shut-off valve pressure tapping.
•
Attach one 12" scale manometer to the outlet side of the second main gas shut-off valve pressure tapping.
•
Attach one 12" scale manometer to — Pull rubber tube from air pressure switch off the aluminum tubing and
connect the manometer using a tee.
Turn Off Main Gas Valve;
2.3 Check the Gas Supply Pressure
1.
Slowly turn on main gas shut-off valve;
2.
Read the gas supply pressure from the manometer; minimum supply pressure for natural gas is 5” W.C.,
recommended supply is 7” W.C., minimum supply pressure for propane is 11” W.C.
3.
If pressure is > 14" W.C.; Turn off the valve;
