Section: PREPARE THE APPLIANCE

Fire and Asphyxiation

Hazard

Failure to comply with manufacturer’s

instructions could result in damage to the

stainless steel combustion chamber

which can result in re or asphyxiation

hazards.

If retrotting a CG4 to a stainless steel combustion

chamber, check the appliance manufacturers instructions

to determine if a lining is required and comply with their

recommendations.

Assemble the Burner

Gather the Necessary Parts

1. You have already veried that you received all the

components shipped with the burner.

2. In addition to the parts provided with the burner you

will need ¾” pipe nipples (schedule 40, black iron –

do not use galvanized) to make up the connection

to the supply piping, and pipe joint compound. Pipe

lengths must be selected to t your installation. We

recommend a 3” to 6” length between the gas valve

and the union.

Prepare the Chassis

1. Determine whether you must add a bafe using the

appliance’s ring rate and Table 5 on Page 10.

2. If a bafe must be added, open the burner’s top

access cover by loosening the two front screws and

pivoting their clips out of the way.

3. Align the bafe between the two pins on the motor

side of the housing (Figure 6 on Page 13) and

against the housing partition and tap it securely

onto the partition.

4. Determine whether you must change from the 4-slot

air band shipped on the chassis to the blank air

band using the appliance’s ring rate and Table 5.

5. If the air band must be changed, remove the air

proving switch, the shutter and the slotted band

(Figure 7 on Page 14).

6. Install the blank band and return the shutter and

air proving switch in the reverse order from step 5,

tightening the screws securely.

Prepare and Install the Air Tube

1. The air tube may be shipped without the head

installed. If so, align the openings in the swirl vanes

with the ame rod and ignition electrodes and

press the head onto the OD of the air tube until the

head is seated and the screw holes on the sides

align. Use care to avoid bending the swirl vanes or

the front edge of the shroud. Install the retaining

screws packed with the head and tighten securely.

2. Remove 2 screws from the housing end of the air

tube that secure the rear edge of the gas gun.

3. Install the air tube onto the housing with the gas

connection on the top side of the air tube (Figure

8). Install the (4) ¼-20 screws nger tight. Install

the remaining 4 screws. After all 8 screws are in

place tighten them all securely.

4. Route the ignition (black) and ame sensing

(yellow) wires from the air tube into the chassis.

5. Connect the yellow (ame sense) wire from the

air tube to the yellow wire in the chassis, and take

up all slack in the wire by pushing it back into the

electrical box.

6. Connect the black (ignitor) wire to the igniter with

the access cover partially closed. Close the cover,

secure it with its retaining clips, and tighten the clip

screws securely.

Assemble the Gas Valve and Manifold

1. You will need to provide a ¾” schedule 40 black

iron pipe nipple (3” to 6” long is convenient) and

joint compound to complete this assembly. Refer to

Figure 9 on Page 15.

2. Install the factory assembled burner manifold

(mounting block, 2 nipples and elbow)on the

outlet side of the valve (the side the arrows point

towards), following the valve manufacturer’s piping

instructions supplied with the valve.

3. Install a ¾” pipe nipple and union on the inlet side

of the valve, following the valve manufacturer’s

piping instructions supplied with the valve.

The gas valve is sensitive to

its installation orientation.

It must only be installed in horizontal piping

with its electrical connections on top as

shown in Figures 9 and 10.

Explosion, Fire, and Gas

Leak Hazard

y Do not disassemble gas valve

y Do not use Teon tape on gas piping.

Damage to gas valve seats and bodies

could cause gas leaks and result in

asphyxiation, explosion, or re.

y Valve must be installed with ow direction arrow

pointing to burner.
