American Flame: AF-LMF Series Valve Kits
Rev. 4-26-21 Page 3
WARNING
This control system must be installed exactly as outlined in these instructions. Read all instructions completely before attempting
installation. Follow instructions carefully during installation. Any modifications of this control or any of its components will void the
warranty and may pose a fire hazard.
These instructions must be used as a supplement to the instructions supplied with the gas log set. Follow the gas log instructions
supplied by the manufacturer on the placement of the burner pan, log basket grate, burner media (sand or vermiculite), ember
material and the log placement. Please follow these instructions on the connection of the inlet line to the gas valve and then to the
burner pan assembly.
If your fireplace installation has glass doors, only operate the fireplace with glass doors in the fully open position.
INSTALLATION: VALVE KIT WITH PRE-EXISTING LOG SET
1. Make sure all gas flow is completely turned
OFF
to the gas log set. Make sure you have a certified and approved shut-off
within 6-feet of the fireplace, or follow local code requirements.
2. Remove all logs and basket grate and set aside.
3. Disconnect the existing manual valve from the inlet gas supply.
4. Remove existing manual valve and fittings on the burner pan.
5. Locate a position on the back of the burner pan about 4-inches from the right or left side of the burner pan to mount the pilot
assembly (Figs. 6-8).
6. Mount pilot assembly to burner pan as shown in Figs. 6-7. Note this pilot bracket clips on the burner pan and holds the pilot
at a 45-degree position onto the pan with no screws required. A screw can be added to secure the pilot assembly if needed.
Carefully bend 1/4” pilot tubing from pilot assembly until the bottom of the pilot bracket is resting against the pan. (This will
hold the pilot at the 45 degree position) then connect pilot fitting to valve.
(Use caution when bending pilot tubing not to
kink the tubing or locate the tubing in or over the burner pan)
.
7. Locate the valve kit in the right or left front corner of the firebox as far forward as possible to maintain clearances
shown in Fig. 8.
8. Bend inlet gas supply line and connect the 3/8” flare fitting to gas valve 3/8” inlet connector (Use caution not to kink the line
when bending).
Note:
Use the UR3-6 adapter to convert to 1/2” fitting if applicable to installation. See Fig. 1.
9. Bend 12” stainless flex line and connect to valve outlet then connect other end to 3/8” flare fitting on burner pan
(Cau tion do
not let gas inlet line to the valve kit or gas outlet line from the valve kit be placed in or over the burner pan).
10. Turn ON gas supply and check all connections for leaks using soapy water solution.
11. Follow valve pilot lighting instructions. After pilot is lit, check pilot fittings for leaks.
12. Reinstall basket grate and logs.
13. Install Damper stop (supplied with this valve kit) on edge of damper to prevent it from fully closing. This allows damper
to remain slightly open to allow the pilot exhaust to vent outdoors.
14.
CAUTION: On all PROPANE installations it is recommended that an inlet pressure regulator be used.
1. Ensure gas is turned OFF to the existing log set before proceeding. Make sure you have a certified and approved shut off
within 6-feet of the fireplace, or follow local code requirements.
2. Follow the instructions supplied with the log set to locate the burner pan. Using the fittings, orifice and gas supply line that
came with the log set, connect the line to the inlet gas supply.
3. Locate a position on the back of the burner pan about 4-inches from the right or left side of the burner pan. See (Figs. 6- 8)
4. Mount pilot assembly to burner pan as shown in (Figs 6 and 7). Note this pilot bracket clips on the burner pan and holds the
pilot at a 45-degree position onto the pan and no screws required. Note: A screw can be added to secure the pilot assembly
if needed. Carefully bend 1/4” pilot tubing from pilot assembly until the bottom of the pilot bracket is resting against the pan.
(This will hold the pilot at the 45 degree position) then connect pilot fitting to valve.
(Use caution when bending pilot tubing
not to kink the tubing or locate the tubing in or over the burner pan)
5. Locate the valve kit in the right or left front corner of the firebox as far forward as possible to maintain the clearances
shown in Fig. 8.
6. Bend inlet gas supply line and connect the 3/8” flare fitting to gas valve 3/8” inlet connector
(Use caution not to kink the line
when bending).
7. Bend 12” stainless flex line and connect to valve outlet then connect other end to 3/8” flare fitting on burner pan (
Cau tion do
not let gas inlet line to the valve kit or gas outlet line from the valve kit be placed in or over the burner pan).
8. Turn ON gas supply and check all connections for leaks using soapy water solution.
9. Follow valve pilot lighting instructions. After pilot is lit check pilot fittings for leaks.
10. Follow the instructions supplied with the log set to install ember material, basket grate and logs.
11. Install Damper stop (supplied with this valve kit) on edge of damper to prevent it from fully closing. This allows damper
to remain slightly open to allow the pilot exhaust to vent outdoors.
12.
CAUTION: On all PROPANE installations it is recommended that an inlet pressure regulator be used.
