Safety and Warning Information
Children and adults should be ALERTED to the hazards
of high surface temperature and should STAY AWAY to
avoid burns or clothing ignition. Young children should be
CAREFULLY SUPERVISED when they are in the same
room as the appliance.
DO NOT place furniture or any other combustible
household objects within 36” of the fireplace front.
READ and UNDERSTAND all instructions carefully before
starting the installation. FAILURE TO FOLLOW these
installation instructions may result in possible fire hazard
and will void the warranty.
Prior to the first firing of the fireplace, READ the Owner’s
Information section of this manual.
DO NOT USE this appliance if any part has been under
water. Immediately, CALL a qualified service technician
to inspect the unit and to replace any part of the control
system and any gas control that has been under water.
THIS UNIT IS NOT FOR USE WITH SOLID FUEL.
Installation and repair should be PERFORMED by a
qualified service person. The appliance and venting
system should be INSPECTED before initial use and at
least annually by a professional service person. More
frequent cleaning may be required due to excessive lint
from carpeting, bedding, etc. It is IMPERATIVE that the
unit’s control compartment, burner, and circulating air
passageways BE KEPT CLEAN to provide for adequate
combustion and ventilation air.
Always KEEP the appliance clear and free from
combustible materials, gasoline, and other flammable
vapors and liquids.
NEVER OBSTRUCT the flow of combustion and
ventilation air. Keep the front of the appliance CLEAR
of all obstacles and materials for servicing and proper
operation.
Due to the high temperature, the appliance should be
LOCATED out of traffic areas and away from furniture and
draperies. Clothing or flammable material SHOULD NOT
BE PLACED on or near the appliance.
This unit MUST be used with a vent system as described
in this installation manual. NO OTHER vent system or
components MAY BE USED.
This gas fireplace and vent assembly MUST be vented
directly to the outside and MUST NEVER be attached to a
chimney serving a separate solid fuel burning appliance.
Each gas appliance MUST USE a separate vent system.
Common vent systems are PROHIBITED.
INSPECT the external vent cap on a regular basis to
make sure that no debris, plants, trees, shrubs are
interfering with the air flow.
The glass door assembly MUST be in place and sealed
before the unit can be placed into safe operation.
DO NOT OPERATE this appliance with the glass door
removed, cracked, or broken. Replacement of the glass
door should be performed by a licensed or qualified
service person. DO NOT strike or slam the glass door.
The glass door assembly SHALL ONLY be replaced as a
complete unit, as supplied by the fireplace manufacturer.
NO SUBSTITUTE material may be used.
DO NOT USE abrasive cleaners on the glass door
assembly. DO NOT ATTEMPT to clean the glass door
when it is hot.
TURN OFF the gas before servicing this appliance. It is
recommended that a qualified service technician perform
an appliance check-up at the beginning of each heating
season.
Any safety screen or guard removed for servicing MUST
BE REPLACED before operating this appliance.
BE CAREFUL not to put any decorating objects sensitive
to heat too close near or above the fireplace as it gets
very hot when operating.
DO NOT use this heater as a temporary source of heat
during construction.
NOTE: When operating your new fireplace for the first time, some vapors may be released due to the burning of curing
compounds used in the manufacture of the appliance. They may cause a slight odor and could cause the flames to be the
full height of the firebox, or even slightly higher, for the first few hours of operation. It is also possible that these vapors
could set off any smoke detection alarms in the immediate vicinity. These vapors are quite normal on new appliances. We
recommend opening a window to vent the room. After a few hours use, the vapors will have disappeared and the flames
will be at their normal height.

Rear Vent Connection—Vertical Vent Rise with
Horizontal Rear Termination
See figure 7.
Can be used with either #551DVK standard vent kit or
another terminal cap and accessories.
Adapter #817VAK, two 90º elbows and pipe lengths will be
required. See venting accessories list on pages 39–40 for
allowable components.
The location requirements are shown in the table and graph
below and figure 7.
For installations with a horizontal rear termination, the
combination of horizontal and vertical vent pipes must
be within the allowed area shown in Graph 1. A minimum
vertical pipe run of 12” is necessary.
Example a: If a vertical rise of 3’ is required, the horizontal run must not be more than 7’9”.
Example b: If a horizontal run of 3’6” is required, the vertical run must be at least 1’9”.
If the horizontal pipe run is redirected using a further 90° elbow, the maximum total horizontal run allowed is
reduced by 3’ to 7’. Redirection using 45° elbows reduces the maximum total horizontal run by 18” per elbow.
Rear Vent Connection—Vertical Vent Rise with Horizontal Snorkel Termination
For “semi-basement” situations where a snorkel accessory alone does not raise the termination sufficiently above ground
level. The dimensional requirements in the section above, figure 7, and graph 1 apply.
Adapter #817VAK, two 90° vent elbows, pipe lengths and a snorkel termination will be required. A thimble kit may also be
necessary. See venting accessories list on pages 39–40 for allowable components.

Note
The distance from the roof to the lowest terminal discharge opening depends on the roof pitch and must be in
accordance with the manufacturer’s instructions supplied with the termination unit.
The venting system for these appliances is considered to be a Special Venting System. The rule in the Natural Gas
and Propane Installation Code CAN/CGA-B149 requiring a minimum vent height of 2’ above any portion of a building
within 10’ does not, therefore, apply.

Rise (Ft)
(D in Fig. 12)
Figure 12
Graph 2
For installations with a horizontal rear termination, the
combination of horizontal and vertical vent pipes must
be within the allowed area shown in Graph 2. A minimum
vertical pipe run of 6” is necessary.
Example a: If a vertical rise of 2’6” is required, the horizontal
run must not be more than 8’.
Example b: If a horizontal run of 3’6” is required, the vertical
run must be at least 1’3”.
The horizontal vent pipe run may be redirected by using
elbows up to a total of 180° but the maximum horizontal
run (E in figure 7 & graph 1) is reduced by 18” for every
45°. For example, if two 90° elbows are used as in
figure 13, the maximum horizontal run is reduced by 3’
per elbow—total reduction = 6’.

Top Vent Connection—Through the Roof
Termination*
See figure 16.
Adapter #817VAK, pipe lengths, a vertical vent terminal
and roof flashing will be required. Various other ceiling or
roof items may be necessary depending on the particular
installation. See venting accessories list on pages 39–40 for
allowable components.
Top Vent Connection—Offset and Through the
Roof Termination*
See figure 17.
For situations where offset is necessary in an attic to avoid
obstructions or allow useful space.
Adapter #817VAK, two 45° vent elbows, wall straps, pipe
lengths, a vertical vent terminal and roof flashing will
be required. Various other ceiling or roof items may be
necessary depending on the particular installation. See
venting accessories list on pages 39–40 for allowable
components.
*Note
The distance from the roof to the lowest terminal
discharge opening depends on the roof pitch and must
be in accordance with the manufacturer’s instructions
supplied with the termination unit.
The venting system for these appliances is considered
to be a Special Venting System. The rule in the Natural
Gas and Propane Installation Code CAN/CGA-B149
requiring a minimum vent height of 2’ above any portion
of a building within 10’ does not, therefore, apply. See
figure 17a.

Vent Location
The vent terminal must be located on an outside wall or through the roof.
This direct vent appliance is designed to operate when an undisturbed airflow hits the outside vent terminal from any
direction.
The minimum clearances from this terminal that must be maintained when located on an outside wall are shown in
figure below. Any reduction in these clearances could result in a disruption of the airflow or a safety hazard. Local
codes or regulations may require greater clearances.
The vent terminal must not be recessed into a wall or siding.
The vent terminal should be positioned where any snowdrifts will not cover it.
Sidewall vent terminations within 7’ of grade require a terminal guard when used with a 551DVK.
