Installation Requirements; Installation Instructions - Suburban SW10D Installation And Operation Manual

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.
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 differences in vinyl siding, this appliance should not
be installed on vinyl siding without first 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 off all electrical and gas supply to the appliance.
CAUTION: Do not install this appliance to where the vent terminates below
a slide-out. This appliance is not to be installed under any overhang. It
must be free and clear of any type overhang.
This installation must conform with the requirements of the authority having
jurisdiction or in the absence of such requirements with the latest edition of the
National Fuel Gas Code ANSI Z223.1/NFPA 54; and the latest edition of the
American National Standard for Recreational Vehicles-NFPA 1192. In Canada
the installation should conform with the following standards.

The appliance and its gas connections shall be leak tested before placing the
appliance in operation.
All air for combustion must be supplied from outside the structure. Air for
combustion must not be supplied from occupied spaces.

INSTALLATION INSTRUCTIONS

Minimum clearance from combustible construction on sides, top, floor and
rear = 0 inches. Provide room for access to rear of heater for servicing.
Provide an opening flush with floor in outer wall of coach as shown. Wall of
coach should be framed as shown in Figure 1. Maintain inside dimensions listed
below. Do not install on carpet unless the carpet is covered by a metal or wood
shield covering the entire area underneath the water heater. If you prefer, you
may cut away the carpet from this area.
INSTALLATION USING FLUSH MOUNT FRAME & DOOR
(See Figure 2 for Illustration)
A. Position heater into framed opening as illustrated. Slide unit into opening until
the front of the control housing is flush with the exterior coach skin.
B. Secure the control housing to the coach wall (framed opening) at the top and
sides of control housing compartment using screws or other suitable fasteners.
Recess the screws or fasteners back far enough from the front edge of control
housing (approximately 1 1/2") in order to clear the flange on door frame. The
door frame, when installed, must not overlap onto screw or other fastener head.
If due to the wall thickness, it is not possible to secure the water heater without
covering the fastener head with the door frame, it is important to not over tighten
the fastener and distort the control housing. Over tightening of the fastener may
cause water heater leaks between the control housing and the door frame.
NOTE: Caulk around screw or fastener heads to assure water tight seal.
C. Install chocks, one on each side of water heater, as illustrated in Figure 1A.
D. On mesa or yoder type sidewalls, flatten the wall area around the opening.
E. Caulk around framed opening (trailer skin) as illustrated.
F. Caulk around door frame using 2 beads of silicone caulking (or suitable
caulking) - one on flange to seal to control housing and one around back side of
frame to seal to coach skin. (See detail A in illustration.)
G. Insert door frame into control housing and secure with four (4) No. 8-15 x
3 1/2" screws provided.
H. To install door, place the two holes in the bottom of the door over the door
pins on the frame. Close the door so that the latch protrudes through the slot in
the door. Turn latch 90 degrees to fasten door.
I. The module board on models SW10D, SW10DE, SW12D, SW12DE, SW16D
and SW16DE is not secured to the water heater. It is to be permanently mounted
by the installer.
The module board must be mounted to where it is accessible for service yet out
of way of children. It should be located in a place where it cannot be subjected to
moisture, cleaning chemicals, flammable vapors and liquids, etc.
The board 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.
MAKING WATER CONNECTIONS
A. Water connections are made at the rear of the water heater. Refer to Figure
3 for all models except SW10DM, SW10DEM, SW12DEM and 16DEM. For
SW10DM and SW10DEM, SW12DEM AND SW16DEM, refer to Figure 4 or 5.
Connect the hot and cold water lines to the 1/2" female pipe fitting provided on
rear of tank. These fittings are marked "HOT" and "COLD". NOTE: Inside each
fitting is a plastic fill tube. Its purpose is to enhance water circulation. DO NOT
REMOVE PLASTIC FILL TUBE.
IMPORTANT: Use a pipe thread compound suitable for potable water or pipe
thread tape on all connections to assure they will not leak.
B. For ease of removal, it is suggested that a pipe union be installed in each
water line.
C. Fill tank with water. Open both hot and cold water faucets to expel air from
tank. When tank is filled and water flows from faucets, close both faucets and
check all connections for leaks.
CAUTION: If you use air pressure to check for leaks, the pressure must not
exceed 30 PSI in accordance with NFPA 1192.
NOTE: After leak testing, drain water from tank.
MAKING GAS CONNECTIONS
Connect a 3/8" gas supply line to the 3/8 flare fitting at gas valve located in the
control housing. When making the gas connection, hold the gas fitting on the
valve with a wrench when tightening the flare nut. Failure to hold fitting secure
could result in a gas leak due to fitting being damaged. NOTE: It will be necessary
to remove the grommet from the control housing, make the gas connection at the
valve, then reinstall grommet.
WARNING! It is imperative that grommet and gas line through grommet
be caulked air tight. If not tightly sealed, moisture and potential harmful
flue products could vent through opening and into living area of trailer.
(See Figure 6.)
B. Turn on gas and check all fittings and connections for leaks, using a soap and
water solution. Correct even the slightest leak immediately.
WARNING! Do not use an open flame to check for leaks
