3. If the fireplace is properly positioned on the
brackets the vent starter pipe and vent heat
shields should be concentric when viewed
through the vent pass-through in the wall. Go
outside and look in the hole to confirm this. If
you are mounting the fireplace on a 45°
partition wall, look in the pass-through using a
mirror if needed.
4. If the vent starter pipe and vent pipe heat
shields do not appear to be concentric, check to
be sure that the mounting tabs on the fireplace
are all fully engaged in the brackets on the
are
lagged to the wall structure. With a helpe
up and align the mounting plate over the gas
supply line and line up with the four mounting
lag bolt pilot holes. These holes are in rece
bosses. Use either the 16” or 24” on center
holes depending on the construction of the wa
Using the lag bolts and washers provided with
the fireplace, install the top lag bolts (with
washers) first, followed by the lower ones. Use
a 7/16” socket wrench to tighten the lag bolts.
Note: It may be helpful to
of dish or hand soap on the lag bolts to
reduce resistance when tightening.
7. At this point, check to be sure that there is
5/16” air gap between the entire flat back
surface of the mounting plate and the wall
surface. The gap is critical to a safe installation,
so if the gap is obstructed in any way,
the obstruction before proceeding.
Next check that the brackets on the mounting
plate that actually hold the fireplace are level,
again using a spirit level.
If the brackets are not perfectly level, you can
adjust the right bracket by loosening the bracket
fasteners and moving the bracket until it is level
with the left bracket. Remember
bracket fasteners once you have achieved a
level position.
10. The next step is to install the vent starter pipe
onto the fireplace.
First, you should remove the glass frame from
the front of the firebox by unclipping the clips on
the side. While holding the frame, gently lift it up
and out of the groove on the bottom. Set the
glass frame aside in a safe flat place.
Carefully place the fireplace with the front down
on a protected floor.
13. Place the vent starter pipe gasket on the back
of the fireplace aligning the holes in the gasket
with the pilot holes on the rear of the fireplace.
14. Align the inner pipe of the vent starter pipe with
the exhaust outlet pipe on the fireplace. The
vent pipe will fit tightly over the fireplace pipe.
Gently push the starter pipe on to the fireplace
pipe until the outer pipe flang
with the starter pipe gasket. Be sure that th
holes in the starter pipe flange align with the
gasket and pilot holes. When the flange
contacts the gasket, install the four fasteners
provided with the starter pipe.
Now you are ready to install the fireplace on the
mounting plate. This will require a helper as the
fireplace is quite heavy.
Lift the fireplace up and guide the vent pipe into
the vent pipe opening in the mounting plate.
The vent pipe must be at the highest locatio
possible in the vent pipe opening (almost
touching the inner vent pipe heat shield) to
allow the mounting tabs on the rear of the
fireplace to clear the top of the mounting
brackets on the mounting plate.
While looking in from the sides, guide the upper
and lower mounting tabs on the back of
fireplace into the corresponding brackets on
mounting plate. When the tabs and brackets
are aligned, push the fireplace down and in to
engage the tabs in the brackets. Note: The
weight of the fireplace is carried only on the top
brackets. The bottom brackets function simply
to keep the bottom of the fireplace from moving
