THIS GAS APPLIANCE MUST HAVE ITS OWN VENT. DO
NOT INTERCONNECT IT WITH ANY OTHER APPLIANCE.
• To ensure proper venting action, this appliance must
be properly connected to a 3” diameter type B-1 vent or
a listed chimney liner. (see Liner Installation Instructions,
Page 5 &6). Minimum vent height 8’ vertical.
• Refer to the latest edition of the National Fuel Gas Code
ANSI Z223.1 (USA) or CSA B-149 (Canada) for proper
vent installation.
• Remove any chimney flue damper or permanently block
it open.
• Chimney should be cleaned and inspected before
installation.
• Chimney cleanouts must be tight fitting or be sealed to
prevent air from leaking into the chimney.
• This appliance is equipped with a built-in backflow diverter
(draft hood). No additional draft hood is required for the
installation.
• The draft hood is designed to be located in the same
atmospheric pressure zone as the combustion air inlet.
Do not block openings in front face to fireplace cavity.
• The B-1 Vent or listed liner can be installed directly on
top of the flue collar of the appliance. The inner flue of
the vent fits outside the flue collar. (See illustration be
low.) The vent is then secured with three sheet metal
screws.
• This appliance needs fresh air for safe operation and
must be installed so there are provisions for adequate
combustion and ventilation air. Follow the latest edition
of ANSI Z223.1 (USA) or CSA B-149 (Canada)
requirements.
• Check periodically that the vent is unrestricted and a
proper draft is present when the unit is in operation. (See
“Checking Proper Vent Action,” Page 7).

d. Guide flue collar into position as you continue to in-
sert appliance.
e. Resecure with mounting screw.
f. Upon completion of installation, check for proper vent-
ing action.
1. Make sure chimney has been cleaned and inspected.
2. Remove flue damper or permanently block open if it is
large enough to allow for passage of the 3” flue liner.
3. Insert chimney liner from top of chimney and attach
to the flue collar of the appliance using at least 3 sheet
metal screws or a clamp.
Masonry Installation:
If fireplace opening size limits
access, follow this procedure (see illustration page 6) to
allow flue collar to be connected to vent before appli-
ance is inserted into cavity.
Any 3” chimney liner (single or double wall) approved for
use with gas appliances can be used with the appliance.
Follow all installation instructions, warnings and clear-
ances to combustibles as provided by the liner manufac-
turer.
LINER INSTALLATION INSTRUCTIONS
As with any natural drafted appliances, the vent cap
must always extend a minimum of 2’ above any struc-
ture within a 10’ horizontal plane.
