LOG REMOVAL

Carefully remove the log set and ember material from around the

burner and place them outside the combustion chamber.

BURNER, MAIN BURNER ORIFICE, AND

PILOT ORIFICE CONVERSION

1. Open stove lower control door. This allows access below fire-

box to gas line connections and gas control valve.

2. Disconnect flare fitting connected to the brass elbow from the

underside of stove insert. Use a 3/4" open end wrench on the

flare fitting (see Figure 3).

3. Turn brass elbow and main burner orifice counterclockwise to

remove from burner. The main burner orifice is threaded into

the burner inlet. The brass elbow may have a slight resistance

since the main burner orifice has been sealed with RTV sili-

cone. Use a 7/8" open end wrench or channel lock pliers for

brass elbow and main burner orifice removal.

4. Remove existing main burner orifice from brass elbow and re-

place with main burner orifice supplied with conversion kit.

Note:

The new main burner orifice will have the number 151 (#39)

stamped on it for identification purposes. Apply a small amount

of thread sealant to the main burner orifice before tightening

(see Figure 4). Sealant must be resistant to propane/LP gas.

5. Remove the burner by loosening the two 5/16" hex mounting

screws (see Figure 3). Lift burner up and out.

6. Convert the pilot burner by changing out the quick change ori-

fice.

Note:

It is not necessary to remove the pilot gas tube for

conversion. Using a 7/16" open end wrench, turn pilot target

hex fitting counterclockwise and remove (see Figure 5).

7. Remove original pilot orifice using needlenose pliers or fin-

gertips. Replace with the pilot orifice supplied with conversion

kit.

Note:

The new pilot orifice has 018 N stamped on it for

identification purposes (see Figure 6).

8. Place open end of conversion pilot orifice into pilot barrel

(see Figure 5).

IMPORTANT:

Make sure the pilot orifice is properly mated

and aligned inside pilot barrel.

9. Replace pilot target removed in step 6. Tighten pilot target

hex fitting until the pilot target aligns with the thermopile

(see Figure 7).

10. Replace original burner with burner supplied with conversion kit.

This new burner for natural gas will have two(2) primary air

holes near the burner inlet (see Figure 3, page 2). Attach with the

two 5/16" hex mounting screws removed in step 5, page 2.

11. Attach main burner orifice and brass elbow assembly to burner.

Place main burner orifice into threaded end of burner and turn

clockwise to tighten (see Figure 3, page 2). Align the brass

elbow with the flare fitting on the aluminum tubing.

12. Reconnect the aluminum tube/flare fitting onto the brass elbow

(see Figure 3, page 2).

13. Reapply RTV silicone to seal area where orifice passes through

the bottom combustion chamber (see Figure 3, page 2).

GAS CONTROL VALVE CONVERSION

Convert the gas control valve by swapping out the valve regulator

portion of the gas valve.

1. Open lower control door on stove to allow access to gas con-

trol valve.

2. Remove the three mounting screws fastening the regulator as-

sembly to the gas control valve and discard (see Figure 8).

3. Remove tower, spring, and diaphragm assembly from control

valve (see Figure 8).

4. Attach new regulator assembly to gas control valve using the

three mounting screws from kit. Tighten screws securely (ap-

proximately 25in-lbs.) (see Figure 8).

5. Install enclosed identification label to valve body where it can

be seen.

6. Connect gas to stove, light stove and test for leaks using non-

corrosive leak detection fluid (see owner’s manual). Bubbles
