INSTALLATION USING FLUSH MOUNT FRAME & DOOR
(S ee Figure 2 for Illustration)
A. P osition heater into fram ed opening as illustrated. S lide 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 (fram ed opening) at the top and
Figure 1
sides of control h o u sin g com partm ent using screw s or other suitable fasteners.
R ecess the screws or fasteners back far e no ug h from the front edge of control
housing (approxim ately 1 1/2") in order to clear the flange on door fram e. The door
fram e, when installed, m ust 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 fastene r h ea d with the door fram e, it is im portant to not over tighten the
fastener and distort the control housing. O ver tightening of the fastener m ay cause
water heater leaks between the control housing and the door fram e.
N O T E : C aulk around screw or fastener heads to assure water tight seal.
C . Install chock s, one on each side of water heater, as illustrated in Figure 1A .
D . On m esa or yoder type sidewalls, flatten the wall area around the opening.
E . Caulk around fram ed opening (trailer skin) as illustrated.
F. C aulk aro u n d d o or fram e using 2 beads of silicone caulking (or suitable
caulking) - one on flange to seal to control housing and one around back side of
fram e to seal to coach skin. (S ee detail A in illustration.)
G . Insert door fram e into control housing and secure with four (4) N o. 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 fram e. C los e the d oor so that the latch protrudes through the slot in the
door. T urn latch 90 degrees to fasten door.
I. The m odule board on m odels S W 12D, S W 16D and S W 12DE , S W 16DE is not
secured to the water heater. It is to be perm anently m ounted by the installer.
T he m odule board m ust be m ounted to where it is accessible for service yet out
of way of children. It should be located in a place w here it cannot be subjected to
m oisture, cleaning chem icals, flam m able vapors and liquids, etc.
T he board and all wiring to the board m ust be protected in order to prevent
dam ages and a cc idental contact with these parts. The m odule board m ay be
m ounted with two (2) N o. 6 x 5/8 screws or other suitable hardware.
MAKING WATER CONNECTIONS
A. W ater connections are m ade at the rear of the w ater heater. R efer to Figure
3 for all m odels except SW 12DE M , SW 16DE M . For SW 12D E M , SW 16DE M , refer
to Figure 5. C onnect the hot and co ld w ater lines to the 1/2" fem ale pipe fitting
provided on rear of tank . T hese fittings are m arked "H O T " and "C O LD ". N O T E :
Inside each fitting is a plastic fill tube. Its purpose is to enhance water circulation.
D O N O T R E M O V E P LAS TIC FILL TU B E .
IM P O R T A N T: U se a p ipe thread com pound suitable for potable water or pipe
thread tape on all connections to assure they w ill not leak .
B . For ease of rem oval, it is suggested that a pipe union be installed in each water
line.
C . Fill tank with water. O pen both hot and cold water faucets to expel air from
tank. W hen tank is filled and water flows from faucets, close both faucets and
check all connections for leak s.
C AU TIO N : If you use air pressure to check for leaks, the pressure m ust not
exceed 30 P S I (in accordance w ith 4-9.1.1 of AN S I A119.2).
N O T E : After leak testing, drain water from tank .
MAKING GAS CONNECTIONS
A . C onnect a 3/8" gas supply line to the 3/8 flare fitting at gas valve located in the
control hous ing . W hen m aking 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 dam aged. N O T E : It will be necessary
to rem ove the grom m et from the control housing, m ake the gas connection at the
valve, then reinstall grom m et.
W AR N IN G ! It is im perative that grom m et and gas line through grom m et be
caulked air tight. If not tightly sealed, m oisture and potential harm ful flue
products could vent through opening and into living area of trailer. (S ee
Figure 6.)
B . T urn on gas and check all fittings and connections for leaks, using a soap and
water solution. C orrect even the slightest leak im m ediately.
W AR N IN G ! D o not use an open flam e to check for leaks
