LP GAS PRESSURE REQUIREMENTS
Inlet and manifold gas pressure checking taps are located on gas valve. These ports are only accessible from the outer left
side of the fireplace. A qualified installer shall take pressure measurements at these ports to verify and set the correct gas
pressures during the LP Kit installation and before fascia materials are installed over the front of this fireplace. Manifold
pressure must be taken at the “MANIFOLD PRESSURE" tap and inlet pressure at the "INLET PRESSURE" tap
with the
burner
operating
by a qualified installer.

LPG PROPER INPUT RATES
With the proper orifices installed, as specified above,
this fireplace utilizing LP Gas will have a maximum
input rate of 33,000 Btu/Hr.
LEAK TESTING REQUIREMENTS
Prior to completing the conversion process, check for
gas leaks with soap and water solution at all plumbing
joints prior to placing this appliance into operation. It
is recommended that all gas-plumbing joints, factory
installed and field installed are checked for leaks.
PILOT FLAME AND MAIN BURNER RELATIONSHIP VERIFICATION
Prior to completing the conversion process, the qualified service technician must, light
the pilot light and verify the relationship between the pilot light flames and the main burners. The pilot light flames directed
towards the propagation ports on the rear and front burner must overlap the propagation ports on the burners. The pilot
light flames must be a minimum of ¾” long and must overlap the propagation ports on both the rear and front burners as
shown in the diagram, below. Verify that the burner tubes ignite quickly and the burner flames propagate smoothly along
the entire length of the burners.
PILOT FLAME LENGTH ADJUSTMENT
If the pilot light flame length is too short and the system
does not maintain a standing pilot, a qualified installer
may increase the length of the pilot light flames to meet
the two requirements: Minimum pilot light length to
maintain a standing pilot light and the pilot light flames
must be long enough to overlap the front and rear
burner ports, 1 inch long minimum.
