Conversion Kits are available to convert to the alter-
nate fuel.The kit contains all the necessary compo-
nents needed to complete the task and ensure safe
operation, including labels that must be affixed to the
stove.

Fuel Conversion Procedure
1. Turn off gas supply to the stove and disconnect
from electrical power source.
2. Remove the glass frame using the 4 mm hex key
supplied with the stove. See fig. 1.
3. Loosen the primary air shutter wingnut and push
the stem all the way back. Fig. 2.
4. Pull the Burner Plate forward to disengage it from
the burner orifice and lift it out of the firebox.
5. Locate the main burner injector. See fig. 4. Slide
the Air Shutter out of the way and use a 1/2”open
end wrench or deep-well socket to remove the
burner orifice from the brass orifice holder. Replace
with the orifice supplied in the kit.Tighten securely.
6. Change the Air Shutter position: Lift the shutter
tube up in its hinge pin slots and turn the tube
over, so that the appropriate fuel type indicator
(LP or NG) is oriented facing you. See fig. 3. Push
the shutter all the way back over the injector.

7. Change the Pilot Orifice. Pull the Pilot Hood off
of its base. It will snap by the retainer clip shown
in Fig. 4. Using a 4 mm allen wrench, unscrew
the pilot orifice. Replace it with the orifice from
the kit. Be sure the new orifice is tightly secured
to prevent by-pass leakage.
Replace the pilot hood. Use a small, flat
head screwdriver to pry back the retainer clip
and then re-insert the head onto the base.
8. Reinstall the Burner Plate by engaging the ven-
turi tube with the Air Shutter. BE CERTAIN THE
BURNER IS LEVEL AND SECURELY SEATED ON THE
SUPPORT LEGS ON THE FIREBOX FLOOR.
9. Replace the variable regulator. Using a Torx T-20
screwdriver, remove the two specialty screws
from the regulator tower on the front of the
valve.Note:To help identify which screws to remove,
refer to the new regulator in the kit.See fig.4.
10. Remove the regulator tower and the rubber dia-
phragm. Be sure to remove the black rubber gasket
from the valve.
11. Install the new variable regulator tower from the
kit. Be sure that the gasket is properly positioned
and tighten screws securely.
12 . Apply the identification labels to the stove so that
they can be seen by any person that may be servic-
ing the stove.
•Label “A”: Applytofrontlip of the valvecompartment.
• Label “B”: Apply to the Rating Plate.
• Small valve sticker: Apply to valve.
13. Install the accessory panels and burner media as ap-
propriate.See pages 19-21 of the Owner’s Manual.
14. Apply anti-seize lubricant to the socket head glass
frame screws before reinstalling the glass frame.

15. Use an electronic gas detector or soap solution
to test for leaks at the pilot head and all gas line
joints. NEVER USEANOPEN FLAMETOCHECKFOR GAS
LEAKS.
16. Pressure Test:
The gas line must be isolated from the gas supply
line by closing the main supply manual gas shut-
off valve (gas cock) during any pressure testing of
the gas supply piping system that is equal to or
exceeds pressures of 1/2 psig (3.5 kPa).
There are two pressure test points on the front of
the stove control valve where test gauge connec-
tions are made. See fig. 5. Gauge connections are
identified by:
• E for inlet or supply pressure ( the amount of gas
coming to the valve.)
• A for manifold pressure (the amount of gas that is
coming out of the valve to the burner.)
Connect a manometer and take pressure readings
at both test points.The reading must fall within
the ranges specified at below.
Inlet Pressure
MIN MAX
Natural Gas: 5.0 WC (1.24 kPa) 7.0 WC (1.74 kPa)
Propane: 12.0 WC (2.99 kPa) 14.0 WC (3.48 kPa)
Manifold Pressure
MIN MAX
Natural Gas: 1.6 WC (0.398 kPa) 3.5 WC (.87 kPa)
Propane: 6.4 WC (1.59 kPa) 10.0 WC (2.48 kPa)
ALWAYS TEST PRESSURES WITH VALVE REGULATOR
CONTROL AT THE HIGHEST SETTING.

WARNING
DO NOT ALLOW THE INLET GAS PRESSURE TO
EXCEED 14.0” WC (OR 1/2 PSIG) AS SERIOUS
DAMAGE TO THE VALVE MAY RESULT.
Symptoms of incorrect gas pressure include:
Insufficient gas pressure:
• Small pilot flame which can result in insufficient
millivolts.
• Little variation in flame picture between HI and
LO regulator settings.
• Insufficient gas to support more than one appli-
ance causing nuisance outages or gas surges.
Excessive gas pressure:
• Permanent damage to valve causing complete
appliance shut down.
• Too large a pilot flame resulting in overheating
of the power generator and consequent shut
down.
• Sooting due to impingement and/or incorrect
fuel to air mix.

See Owner’s Manual for examples of flame pictures
for River Rock and Starfire Glass embers.
17. Adjust Primary Air Shutter and Flame Picture.
Slide the shutter stem back to decrease air and
forward to increase air supply to the injector.
For either fuel, start at the half-way setting, and
let the burner settle-in for 15-20 minutes before
making any adjustments. Make adjustments
in 1/8” increments, letting the burner settle-in
again before making each subsequent adjust-
ment.
