UltraGlow G36D Zero Clearance Direct Vent Gas Fireplace

"C" Screw Position:
For a facing material depth of 1-1/4"
(32mm), the top facing support must be
reversed.
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
The Top Facing Support, the Side Nailing Strips
and the 2 Top Standoffs must be correctly po-
sitioned and attached to the top before unit is
slipped into position.
Top Standoff Assembly
The top standoffs are shipped in a fl at position
and must be folded into shape and attached.
1) Remove the standoffs from the fi replace
top.
2) Take each standoff and bend into the correct
shape. Bend up at the bend lines until the
screw holes in the standoff and the pre-
punched screw holes on the fi replace top
line up.
Top Facing Support and
Side Nailing Strips
Determine the total thickness of facing mate-
rial (e.g. drywall plus ceramic tiles) to allow the
fi nished surface to be fl ush with the front of the
unit. Total facing thickness can vary from 1/2"
(13mm) to 1-1/4" (32mm) thick.
The Top Facing Support & Side Nailing Strips can
be mounted in 3 different positions depending
on the thickness of the facing material.
*
For "C" screw position the top facing support
is reversed.
1)
Mount Top Facing Support using the 3
supplied screws into the three pre-punched
screw holes on the top front of the unit. Use
hole positions A, B, or C depending on your
facing depth.
2)
Use the same screw hole position for the
Side Nailing Strips as was used for the Top
Facing Support. Attach each side nailing
strip using 3 screws.
VENTING
INTRODUCTION
The G36D uses the "balanced fl ue" technology
Co Axial system. The inner liner vents products
of combustion to the outside while the outer liner
draws outside combustion air into the combus-
tion chamber thereby eliminating the need to
use heated room air for combustion and losing
warm room air up the chimney.
Note: These
fl ue pipes must not be con-
nected to any other appliance.
The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.

Note: 40-1/2" (1029mm) is the minimum
height for both fl ex termination or
Simpson Dura-Vent venting.
5)
The unit does not have to be completely
enclosed in a chase. The clearance on top of
the unit is 0" to the standoffs so combustible
building materials can be laid directly on top
of the standoffs. You must maintain clear-
ance from the vent to combustible materials
for fl ex, see Vent Clearances, page 7.
6)
Use steel studs for framing where the
1-1/2" (38mm) clearance from the vent to
combustible material cannot be maintained,
e.g. front top header.
INSTALLATION
3) Attach the standoff securely to the top
with 2 screws per standoff (on opposite
corners).
