PRE-START-UP

Filling System-Heating Heaters

Fill system with water. Purge all air from the system using purge valve sequence. After system is purged of air, lower system pressure. Open valves for normal system operation, fill system through feed pressure. Manually open air vent on the compression tank until water appears, then close vent.

Domestic Hot Water Heaters

Purge all air from system before lighting heater. This can be normally be accomplished by opening a down- stream valve.

Inspect Venting System:

1.Check all vent pipe connections and flue pipe material.

2.Ensure vent terminations are installed per code and are clear of all debris or blockage.

Pre-Start-Up Check

1. Verify heater is filled with water.

2. Check system piping for leaks. If found, repair immediately.

3. Vent air from system. Air in system can interfere with water circulation.

4. Purge air from gas line up to heater.

INITIAL START-UP

Tools Needed

One 8–0–8, 16” scale manometer

Two 6–0–6, 12” scale manometers

7/16” open end wrench

1/2” open end wrench

Screwdriver (Standard & Phillips)

3/8” open end wrench

Multi-meter

3/16” Allen wrench

3/32” Allen wrench (Honeywell or White-Rodgers gas valve)

5/32” Allen wrench (Invensys gas valve)

#10 Torx driver w/center hole (Invensys gas valve)

NOTE: Digital manometers are not recommended.

Preparation for Start-Up

WARNING: Do not turn on gas at this time.

Check Power Supply

Fig. 30: Check Power Source

With volt meter at incoming power check voltage between:

Hot - Common (~120 VAC)

Hot - Ground (~120 VAC)

Common - Ground (< 1 VAC)

WARNING: If Common - Ground is > 1 VAC,

STOP: Contact electrician to correct ground failure. Failure to do this may burn out 120V-24V transformer, or may cause other safety control damage or failure.

Attach Manometers to Measure Pressures

Attach 16" scale manometer to the main gas shut- off valve supply pressure tapping.

Attach one 12" scale manometer to the manifold gas pressure tapping. (See gas valve detail on page 7.)

Attach one 12" scale manometer to the tee near the blower housing.
