VENTING 
INTRODUCTION
The  P48-2  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 
combustion chamber thereby eliminating the 
need to use heated room air for combustion and 
losing warm room air up the chimney.
Note: These flue pipes must not be 
connected 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.
* For "C" screw position the top facing support 
is reversed.
"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 
positioned 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. 
3)  Attach the standoff securely to the top 
with 2 screws per standoff (on opposite 
corners).
TOP FACING SUPPORT AND 
SIDE NAILING STRIPS
Determine the total thickness of facing material 
(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.
 
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.
