SECTION N: INITIAL START-UP
1.0TOOLS NEEDED
•One
•Two
•7/16” open end wrench
•1/2” open end wrench
•Screwdriver
•Volt meter
•3/16” Allen wrench
2.0PREPARATION FOR START-UP
WARNING: DO NOT TURN ON GAS AT THIS TIME
2.1Check Power Supply
With volt meter at incoming power check voltage between:
Hot - Common | (~120VAC) |
Hot - Ground | (~120VAC) |
Common - Ground | (< 1VAC) |
If Common - Ground is > 1 VAC - STOP: Contact electrician to correct ground failure. Warning: Failure to do this may burn out
2.2Attach Manometers to Measure Pressures
•Attach 24" scale manometer to the first main gas
•Attach one 12" scale manometer to the manifold gas pressure tapping. (See gas valve detail on page 7.)
•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;
2.3Check the Gas Supply Pressure
1.Slowly turn on main gas
2.Read the gas supply pressure from the manometer; minimum supply pressure is 5” W.C., recommended supply is 7” W.C. for natural gas (minimum 12” W.C. for LP gas).
3.If pressure is > 14" W.C., turn off the valve.
4.Check if the service regulator is installed and/or adjust the service regulator.
