INSTALLATION REQUIREMENTS
WARNING! Installation of this appliance must be made in accordance with the written
instructions provided in this manual. No agent, representative or employee of Suburban or
other person has the authority to change, modify or waive any provision of the instructions
contained in this manual.
Silicone caulking is required in several places to ensure an airtight seal. Suburban
recommends using an industrial grade silicone such as Henkel Teroson SI 9160, Bostik 922,
Selleys 401 or equivalent.
NOTE: Do not install the water heater with the door facing toward the for-
ward end of the coach. See Figures 9, 10 and 11.
CAUTION:
If possible, do not install the water heater to where the vent can be covered or
obstructed when any door on the trailer is opened. If this is not possible, then the travel of the
door must be restricted in order to provide a 6” minimum clearance between the water heater
vent and any door whenever the door is opened.
CAUTION: Due to the di󰀨erences in vinyl siding, this appliance should not be installed on
vinyl siding without rst consulting with the manufacturer of the siding or cutting the siding away
from the area around the appliance vent.
CAUTION: In any installation in which the vent of this appliance can be covered due to the
construction of the RV or some special feature of the RV such as slide out, pop-up etc., always
insure that the appliance cannot be operated by setting the thermostat to the positive “OFF”
position and shutting o󰀨 all electrical and gas supply to the appliance.
CAUTION: Do not install this appliance to where the vent terminates below a slide-out. This ap-
pliance is not to be installed under any overhang. It must be free and clear of any type overhang.
This appliance shall be installed only by authorised persons and in accordance
with the manufacturer’s installation instructions, local gas tting regulations, elec-
trical wiring regulations, local water supply regulations, AS/NZS 5601.2; gas in-
stallations and any other statutory regulations. Installation shall be in accordance
with AS/NZS 3500.4.
1. The appliance shall be disconnected from the gas supply piping system during
any pressure testing of the system.
2. The appliance and its gas connections shall be leak tested before placing the
appliance in operation.
3. All air for combustion must be supplied from outside the structure. Air for com-
bustion must not be supplied from occupied spaces.
4. This unit is a balance ue heater.
5. Discharge pipe must be mounted at the pressure relief valve and installed through
oor line of caravan or motor home, and must be left open to free air so as water
can escape if required and is to be installed in a continuously downward direction
and in a frost-free environment. For convenience, a break -thru grommet has
been provided in the bottom of the control housing. The center of the grommet
may be pierced and piping routed through. After drain line is installed, apply sili-
cone caulking around the grommet and drainline to ensure an air tight seal.
6. A mains pressure reducing valve must be installed in the incoming water line
with a rating of 350 kPa (50 psi). Please Note: Warranty will be void if pressure
reducing valve is not installed.
INSTALLATION INSTRUCTIONS
Keep the heater and ueway at least 25mm clear of anything that is combustible,
like walls, cupboards and timber.
Provide an opening ush with oor in outer wall of coach as shown. Wall of coach

Do not install on carpet unless the carpet is covered by a metal shield at least
50mm greater than the width of the water heater.
INSTALLATION USING HINGED DOOR
(See Figure 2A for models SW4DERA/SW6DERA)
(See Figure 2B for models SW4DRA/SW6DRA)
A. Remove water heater and module board from packaging.
B. In some limited accessibility applications, the chocks as illustrated in Figure
1A must be installed prior to setting water heater into position. Install chocks,
one on each side of water heater, as illustrated in Figure 1A.
C. Position heater into framed opening as illustrated.
D. On mesa or yoder type sidewalls, atten the wall area around the opening.
E. Caulk around framed opening (trailer skin) as illustrated.

and all wiring to the board must be protected in order to prevent damages and
accidental contact with these parts. The module board may be mounted with two
(2) No. 6 x 5/8 screws or other suitable hardware.

FRAME & DOOR
(See Figure 2C for models SW4DEFA/SW6DEFA)
(See Figure 2D for models SW4DFA/SW6DFA)
A. Remove water heater and module board from packaging.
B. On mesa or yoder type sidewalls, atten the wall area around the opening.
C. Caulk around framed opening (trailer skin) as illustrated.
D. Apply a bead of silicone caulking (or suitable caulking) around back side of
door frame. See detail “A” in illustration. This will seal frame to coach skin.
E. Secure intermediate door frame to trailer skin using 11 screws around the
perimeter of the frame.
F. Insert ush door frame into intermediate door frame. Pull frames tight to con-
trol housing using the three (3) No. 8-15 x 3 1/2” screws provided.
