This unit is shipped with a cooling chassis installed in the cabinet. Prior to installing the unit in the wall
opening, the shipping bolts located at the bottom on both sides of the cabinet must be removed to allow
for removal of the cooling chassis. 1/4” hole plugs provided with the unit should be installed in the
holes to prevent air leakage.
Shipping bolts are located on both sides below this sticker:
This unit is designed and approved for through-the-wall installation only. The unit must be
installed a minimum of 8” above finish floor. If this unit is installed in a residential garage, it
must be installed so that the ignition source and burners are located not less than 18 inches
(457 mm) above the floor, and it must be located or protected to avoid physical damage by
vehicles . The entire unit must not be installed outside . The grille side of the unit should extend 3/4”
beyond the exterior wall to allow moisture that may enter the outdoor section to drain. The pitch of the
internal drain pans toward the outside will assure proper drainage when the cabinet is installed level.
Masonry walls must have a lintel to support the wall .
The grille side must be kept free of any obstructions that will reduce or alter the air flow pattern.
If an optional architectural grille is to be used on standard units, the stamped and louvered grille
provided must be removed. Consult the factory prior to ordering product(s) that require an optional
architectural grille.
The interior of the unit may be installed with zero clearances to adjacent combustible surfaces. The
unit shall not be installed directly on carpeting, tile or other combustible material, except wood
flooring . In order to be able to remove the chassis, 29” of open area must be left unobstructed in front
of the access panels. The 3/4” O.D. drain pan connection should be connected to the building drain
using the flexible tubing included and a trap. The secondary drain offers protection from overflow.
The secondary drain feature is piped into the base of the unit and drains through the weep holes
outside. Reconnect 3” piece of clear flexible tubing to secondary drain on drain pan. Position secondary
drain through grommet of chassis and connect to flexible tubing (prime trap prior to operating).
THE SHIPPING BOLTS MUST BE REMOVED PRIOR
TO INSTALLATION OF THE CABINET TO PERMIT
REMOVAL OF THE CHASSIS. INSTALL THE HOLE
