SECTION N: HI-DELTA INITIAL START-UP

1.0TOOLS NEEDED

•One 12-0-12, 24” scale manometer

•6-0-6, 12” scale manometers

•7/16” open end wrench

•1/2” open end wrench

•Screwdriver

•Volt meter

•3/16” Allen wrench

•Jumper cable

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 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;

4.Check if the service regulator is installed and/or adjust the service regulator;
