WARNING - TO REDUCE THE
RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OB-
SERVE THE FOLLOWING:
Recommended for use only over conventional domestic gas and electric ranges, and
1. Remove and discard shipping bracket (attached to motor
mounts and inlet collar). Check to see if blower wheel turns
freely. Do not replace top until installation is complete.
2. Provide a square cutout through the roof (or wall) as shown
by the dashed lines, or cut a round hole to fit duct with a
separate hole for electrical conduit as shown by solid lines
in Fig. 1.
3. Install the remote ventilator with the discharge pointing
down slope as shown in Figures 3 and 4. Follow standard
roofing procedures. Install the ventilator so the discharge
edge is on top of the shingles and the rear edge is
underneath the shingles.
NOTE: The unit must be sealed between the roof (or wall)
and the underside of the flange with roofing mastic to
prevent leaks. For installation on a flat roof, or roofs with
a pitch less than 1-1/2" in 12", install ventilator on the curb
as shown in Fig. 2. Position the curb on flat roofs so that
the discharge (low) end points away from prevailing wind.
4. Connect ventilator to the exhaust system with 8 inch diam.
duct for DHG6003UC and 10" diam. duct for DHG1003UC
and use adjustable elbow to adjust to roof angle. Tape all
joints to prevent air leaks.
5. Connect ducting in the inlet to the ventilator with duct tape.
6. Clearance to combustible material is 0".
