STEP TWO: BURNER INSTALLATION AND GAS SUPPLY CONNECTION
1. Insure that the Gas Supply to the Fireplace is turned off and verify correct gas type and proper gas pressures.
2. Thread 1/2” FIP x 3/8” Flared Elbow (Figure 3A) onto the Gas Supply Pipe (Figure 3B) and wrench tighten.
3. Place Front Logs on grate with flat unpainted sides facing inside of burner and Log Locator Pins facing
up (Figures 3C and 4 below).
4. Place Chillbuster™ inside the firebox or approved enclosure centered from left to right. Remove logs and thread
one end of the supplied Flex Connector (Figure 3A bottom right) to the Valve Input (Figure 3B), then connect the
other end to the 1/2” FIP x 3/8” Flared Elbow (Figure 3C) attached to the Gas Supply Pipe. If Flex Connector is
bent into too small a radius it may kink or break causing air flow noise and /or gas leaks.

MINIMUM AND MAXIMUM INLET GAS SUPPLY PRESSURE
The minimum inlet gas supply pressure shall be 5 inches of water column on Natural Gas and 11 inches of water column on
Propane. The maximum inlet gas supply pressure shall be 7 inches of water column on Natural Gas and 14 inches of water
column on Propane. The appliance and its main gas valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa) and isolated from the gas supply piping
system during any pressure testing at equal to or less than 1/2 psi (3.5 kPa).
WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically
approved with this heater may result in property damage or personal injury.
