WARNING:
Due to the size and weight of this equipment, it
is recommended the heater mounting structure be
reviewed and approved by a qualified structural
engineer before installing this equipment.

Before proceeding with the installation, verify the
feasibility of the location selected with respect to ac-
cessibility to the equipment for service and mainte-
nance functions.

CAUTION
To prevent contaminated air from being drawn
into the heater, install the heater’s inlet at least 10
feet from any building exhaust, process exhaust,
sewer stacks, or other sources that would allow
contaminants to be drawn into the heater. Consult
local codes for additional references.
1. Prepare wall penetration to the dimensions below.
2. Connect the inlet accessories to the heater includ-
ing the filter section (optional).
3. Install structural uprights and associated wall sup-
ports per structural engineers recommendations.
4. Remove the lag bolts used to fasten the unit to the
skid.
5. Utilizing the lifting brackets on the front of the
heater, use a forklift or comparable lifting device
to raise and position the heater. Take precau-
tions to prevent equipment damage (dents and/or
scratches) when the heater is being lifted into posi-
tion.
6. Secure the heater in place with contractor supplied
hardware.
7. Install the wall sleeve to the downturn.
8. Install fiberglass insulation in the gaps around the
wall opening and the wall sleeve. Apply enough
material to accommodate the full thickness of the
wall.
9. Install finish trim pieces (by others) to the top,
sides and bottom of the wall sleeve on both the
inside and outside wall surfaces.
10. Apply silicone caulk at the joint between the wall
sleeve and the outside wall surface. Make certain
this is a continuous bead and that it runs the entire
width of the wall sleeve. Caulk all other exposed
joints.
11. Mount the gas train enclosure to the wall structure
and connect gas piping between the heater and the
enclosure.
12. Install the inlet skirt to the heater inlet and attach
the skirt extension to the exterior wall (page 21).
13. Install wall sleeve, second downturn and
directional elbows. Consult the job layout for the
orientation of the elbows.
* Dimensions allow for 1½” clearance on each side
