Sure Heat MO, SH, CSO - Manual (Page 4)

1. This gas log set 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. The fireplace must be constructed of non-combustible materials and
approved to burn wood. WARNING: Do not burn wood or other material in any fireplace fitted with a gas
log set.
2. To operate this gas log set, the fireplace damper must be fully opened and locked.
3. The smallest or minimum dimension of the chimney flue must be 8 inches in diameter. Do not use an Energy
Efiicient Gas Log Set if it is smaller than 8 inches. Do not use an Energy Efiicient Gas Log Set if fumes from the
burner emerge into the room when the damper is fully open. This indicates that there is not adequate draft for our
log set and the gas log set must not be used until fireplace draft is corrected.
4. This appliance must be installed with a Damper Stop Clamp (Part #14). When operating this gas log set, the flue
damper must be fully open.
WARNING: Improper use or installation may cause Carbon Monoxide Poisoning. Carbon Monoxide, which is
an odorless and colorless gas, is a by-product of combustion. Caution must be taken to insure the fireplace is
properly vented when logs are in use. To avoid having potentially dangerous fumes enter the living area, be sure
the chimney is drawing properly and has sufficient draft.
5. A fireplace screen must be in place when operating this gas log set. This screen shall have an opening(s) for the
introduction of combustion air. If the fireplace has glass doors, operate this gas set with the doors fully opened.
6. The nominal inlet gas pressure for this appliance is 7" water column for natural gas.
7. This gas log appliance and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing at pressures in excess of 1/2 PSIG.
This appliance must also be disconnected from the gas supply system by closing its individual manual shutoff valve
during any pressure testing at pressures equal to or less than 1/2 PSIG.
FIREPLACE PREPARATION
A. Professionally clean chimney and fireplace floor of any
combustible material to limit the smell from the system.
B. Open fireplace damper fully and install Damper Stop Clamp
with 1/4 x 2" set screw (Part #14). This clamp is designed to
allow any pilot combustion by-products to vent (See Figure 2.)
Should the Damper Stop Clamp supplied not fit, a permanent
damper stop clamp must be installed that will keep the damper
open at a distance of not less than 1 1/2". Damper must be in
full open position anytime this unit is in operation.
C. Prior to connecting the gas log set, make sure that the gas
supply to the fireplace is completely shut off.
Installation of this Energy Efficient Gas Log Set and provisions for combustion and ventilation air
must conform with the National Fuel Gas Code ANSI Z21-84 and applicable local codes.
