WARNING
Never use an open flame to check for leaks.
9. Remove the rear and front burner orifices from the manifold
and replace them with the orifices provided in the kit
(Figure 3)
.
NOTE: See Table 6 for burner orifice sizes.
10. Use pipe joint compound or Teflon
®
tape on all pipe fittings be-
fore installing.
NOTE: Ensure propane resistant compounds are
used in propane applications, do not use pipe joint compounds
on flare fittings.
11. Retrieve the burner and hold the venturi tube above the orifice.
Place the shutter adjusting rod in the slot of the shutter arm
(Figure 4A)
. Set the burner assembly into its position and se-
cure with the two screws previously removed.
12. Reinstall the subfloor with screws.
13. Reassemble the remaining components.
14. Turn on gas supply and test for gas leaks, using a gas leak test
solution—also known as bubble leak solution.
NOTE: Using a
soapy water solution is an effective leak test solution but it is
not recommended, because the soap residue that is left on the
pipes/fittings can result in corrosion over time.
A. Light the fireplace (refer to the lighting instructions
label in the control compartment).
B. Brush all joints and connections with the gas leak test
solution to check for leaks. If bubbles are formed, or
gas odor is detected, turn off the appliance. Either
tighten or refasten the leaking connection, and then
retest as described above.
C. When the gas lines are tested and leak free, rinse off
the leak testing solution.
15. Relight the main burner. Verify proper burner ignition and op-
eration. See
Figure 5
. Adjust burner air shutters, if necessary
(see Figures 4A, 4B and Table 3).
16. Inspect the pilot system for proper flame. The pilot flame should
engulf the flame sensor. See
Figure 6
.
17. Using a manometer, test the inlet and manifold gas pressures
(Tables 4 and 5)
.
NOTE: Always test pressures with the valve
regulator control at the highest setting.
18. Affix the appropriate conversion labels
(see Figures 8 and 9).
19. Replace door, barrier and optional facade (if installed) - Ensure
proper operation with both door and barrier in place.
NOTE: A BARRIER DESIGNED TO REDUCE THE RISK OF BURNS
FROM HOT VIEWING GLASS SHALL BE USED DURING OPERA-
TION OF THIS FIREPLACE FOR THE PROTECTION OF CHILDREN
AND OTHER AT-RISK INDIVIDUALS.

BURNER AIR SHUTTER ADJUSTMENT INSTRUCTIONS
1. Adjust the air shutters per instructions in
Figures 4A and 4B
and
Table 3
.
2. Light the fireplace. Follow the lighting procedure on the lighting
label in the control compartment.
3. Allow the burner to operate for at least fifteen (15) minutes while
observing the flame continuously to ensure that the proper flame
appearance is achieved
(Figure 5)
. If the following conditions
are present, adjust accordingly.
• If flame appears weak or sooty, adjust the air shutter,
incrementally, to a more open position until the proper flame
appearance is achieved.
• If flame remains blue, adjust the air shutter, incrementally,
to a more closed position until the proper flame appearance
is achieved.
4. When satisfied that the burner flame appearance is normal,
reinstall the lower control compartment door, then proceed to
finish the installation.
