General Information
This gas conversion kit contains the necessary components for field
conversion of an approved Montigo fireplace from Natural Gas (NG)
to Liquid Propane (LP).This kit is approved for use with the following
Direct Vent (top and rear vent versions) model(s):
 H34D
The conversion of this appliance must conform with local codes or,
in the absence of local codes, with the American National Fuel Gas
Code, ANSI Z223.1, or the Canadian Installation Code, CAN / CGA
WARNING!
This conversion kit shall be installed by a qualified service
agency in accordance with the manufacturer's instructions

CAUTION - Before you begin:
1. Shut off gas at the shut-off valve and disconnect the electrical
supply (if used).
2. Remove the glass door as shown in the installation instructions
and remove the logs. Flip down or remove the lower trims.
Install or Remove the Air Inlet Screw:
3. Locate the two air inlet holes on the burner tube underneath the
right side of the burner tray. On Propane models, both air inlet
holes must be open, and on Natural Gas models the air inlet
screw, provided in the conversion kit, must be installed.
7. Unscrew the coupling assembly from the pan base. The burner
orifice is located at the top end of coupling. Unscrew it and
install the new orifice from the conversion kit to convert to the
new gas, as shown in figure 2b. Re-install all of the gas fittings.

4. When converting to the desired fuel, install or remove the supplied air inlet screw using a 3/16 allen key. The air inlet screw is
accessable on the right side of the burner tray as shown in figure
1.

Converting the Pilot Assembly:
8. Remove pilot hood/ orifice cap by pulling it off the pilot assembly.
The cap will snap off with slight pressure; the orifice must be
removed with an allen key. (See Figure 4)

Converting the Burner Orifice:
6. Disconnect the valve from its valve bracket by removing the 4
screws that hold the valve in place, and disconnect the valve
asssembly from the pan base by spinning off the union as shown
in figure 2a. The valve assembly will drop out of the way, allowing
access to the coupling.

9. Install the new orifice from the conversion kit to convert to the
pilot to the new gas. Tighten the orifice securely with an allen
key. Re-attach the pilot hood, making sure the notch in the hood
lines up with the tab on the pilot assembly.
Checking the Gas Pressure
To check the Inlet and Manifold gas pressures, a Water Column Pressure Gauge with 5/16" dia. tubing can be used. To test the Manifold
Pressure, loosen the screw shown in Figure 7. Attach the gauge to
the Manifold Pressure Test Connection and open the gas shut-off
valve. The tubing must be tight in the connection to prevent gas leaks.
Measure the Manifold Pressure and compare the value against the
chart below.

Turn off the fireplace and close the shutoff valve. Remove the test
gauge. Re-tighten the test connection screw to prevent gas leakage.
Repeat the procedure for the Inlet Pressure.
If the pressure readings are not within the limits set out, contact the
factory. If the pressure readings are correct, ensure that both test connection screws are tightened securely, to prevent a gas leak.
Pilot Burner Adjustment
1. Locate the Pilot Adjustment Screw on the gas control valve. (See
figure 7)
2. Adjust pilot screw to provide properly sized flame as shown in figure 8). To increasethe flame, turn the screw counterclockwise. To
