DGAT & DGAM SERIES FURNACES

Installation Procedure for DGAT & DGAM

Furnaces

The following steps are listed for installation of furnace and

need not be performed in the exact order as listed:

Follow this procedure to avoid serious misalignment of fur-

nace duct connector opening and supply duct.

A. This Furnace requires NO sub--base

For convenience, a template is provided on the furnace

shipping carton. This may be cut out and used to accu-

rately locate furnace, floor and vent openings. See

Figure 12.

Locate template on floor to provide proper clearances to

the walls and the front. Cut 2” diameter hole or small

square hole as indicated on template.

Locate template so that furnace opening outline is cen-

tered over under--floor supply duct as accurately as pos-

sible. This is important because of the limited adjust-

ment from side to side, and from front to rear of the duct

connector.

Locate under--floor duct through hole and center “floor

cut--out opening” on template over duct.

Accurately cut “floor cut--out opening” from template,

mark floor opening, remove template and cut floor on

outside edge of marked line.

Duct connectors will fit opening in any one of four (4) posi-

tions. Place proper duct connector in the opening in the best

position, (duct connector may be shifted in either direction

for best location).

Mark duct opening with a scribe or marking pen, then re-

move duct connector. Cut hole in duct to correct size accord-

ing to dimensions shown in Figure 11. Cut duct accurately to

prevent air leakage.

Reinstall duct connector with tabs inside of hole in the duct

and bend tabs up firmly against underneath side of duct.

Secure duct connector to floor with four (4) sheet metal

screws using holes provided in the connector. See

Figure 14.

B. Install Furnace

Remove panel from air conditioning compartment.

Check to make sure roof jack is not extending too far

down into furnace location. Slide furnace into location

and align over floor opening.

Pre--cut openings and knock--outs are provided in fur-

nace base to install a front fuel line and/or front refriger-

ant lines. If rear entrance lines are to be used, they

must be installed before the duct connector is in -

stalled and secured in place.

For air conditioning lines, remove the knock--out.

C. Securing Furnace

Make any minor adjustments in the furnace location

necessary to insure that the opening in the furnace bot-

tom is centered over the opening in the duct. Secure fur-

nace to floor, as required, through holes at front and rear

of furnace. Holes for screws are located in bottom flange

front corners and rear flanges.

Secure furnace to wall at top by using metal strap pro-

vided. (See Figure 14.)

Manufacturers may add straps equivalent to provided

straps, if required, for securing furnace to structural

member.
