GOLD CGi Gas-Fired Water Boiler — Boiler Manual

2a Prepare boiler — placement & setup

Place boiler/crate near position

1.Leave boiler in crate and on pallet until installation site is ready.

2.Move entire crate and pallet next to selected location.

3.Remove crate.

4.Remove boiler from pallet.

Do not drop boiler or bump jacket on floor or pallet. Damage to boiler can result.

a.Tilt left side of boiler up and place a board under left legs.

b.Tilt boiler the other way and place a board under right legs.

c.Slide boiler backward off pallet and into position.

5.Check level.

a.Shim legs, if necessary.

b.Do not alter legs.

Inspect orifices and burners

1.Remove front jacket door. Remove burner shield (see Figure 40, item 4, page 60).

2.Check for correctly-sized manifold orifices. See Table 2 for sizing. (The orifice size is stamped on the orifice spud barrel.)

Correctly-sized manifold orifices must be used. Failure to do so will result in severe personal injury, death or sub- stantial property damage.

3. Reinstall burner shield.

Do not operate boiler without burner shield in place. Failure to do so could result in severe personal injury, death or sub- stantial property damage.

Orifice replacement procedure

(when required)

1.Remove the screws securing the burner shield and remove burner shield.

2.Using a 7/16” open-end wrench, remove the burner orifices from the manifold.

3.Apply a small amount of pipe dope to each of the new orifices and install in the manifold us- ing a 7/16” open-end wrench. Make sure the ori- fices are aligned correctly, not cross-threaded in the manifold tappings.

Use only pipe dope compatible with propane gas, even if boiler is to be operated on natural gas. Failure to comply could result in severe personal injury, death or substantial property dam- age.

4.Carefully replace the burner shield.

5.Follow the check-out procedure, Section 8 page 36, to assure the boiler is now operating properly after orifices are replaced.
