Sure Heat VMO Vented - Manual (Page 4)

IMPORTANT INFORMATION
The minimum inlet gas supply pressure is 5.5 inches water column for natural gas and 11.0 inches
water column for propane. The maximum allowable inlet gas supply pressure is 10.5 inches water
column for natural gas and 13.0 inches water column for propane. If this appliance is to be supplied
with L.P. gas the tank or bottle supplying the gas must have a regulator that reduces gas pressure
between 11 and 13 inches water column.
WARNING: This appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 PSIG.
The appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during pressure testing of that system at test pressures in excess of
1/2 PSIG.

INSTALLATION TO EXISTING GAS LINE IN FIREPLACE
A manual ON/OFF valve should be present within easy reach of the Gas log set. If a manual valve is
not present, one must be installed prior to the gas log installation.
INSTALLATION IN A MASONRY FIREPLACE
A 1/2” gas supply line must be provided to the fireplace. Most installations require drilling an access
hole through the Masonry wall. The supply line should be secured and sealed by mortar within the
access hole. The supply line should also have an ON/OFF valve in the wall or inside the fireplace.
DAMPER CLAMP INSTALLATION
This appliance is only to be installed and burned in a fully vented fireplace with a fully functional
damper and chimney that is free of any obstructions. A damper clamp is provided to allow any pilot
combustion products to vent. The unit must be operated with the damper in the fully opened position.
