Installation - AquaStar 170 VP Installation And Operating Instructions Manual

8. This heater is not approved for closet instal-
lation. For alcove installation, maintain the fol-
lowing minimum clearances from all construc-
tion for servicing and proper operations:
Alcove
A. Top 12 inches
B. Front OPEN
C. Back 0 inches
D. Sides 6 inches
(Left side 10" for ease of service)
E. Floor 12 inches*
F. Flue 6 inches (single wall only)
*Do not install over floor covering which is combustible,
such as carpet.
Minimum clearance to combustible materials
should not be less than 6" for single wall flue
pipe. Note that this clearance can be reduced
if combustible materials are protected as per
table VI of the National Fuel Gas Code or if Type
B gas vent is used. (Follow the minimum
clearances for the vent type. We recommend
the use of Type B gas vent).
9. WARNING: THIS WATER HEATER DOES
NOT STORE ANY HOT WATER. DO NOT IN-
STALL IN AN AREA WHERE IT COULD
FREEZE. This heater is neither designed for
nor approved for outside installation.
10. The heater must be level before you begin
the piping.

INSTALLATION

Before installing the unit, be certain your heater is
for your type of gas - Propane or Natural Gas.
Identification labels for type of gas are found on the
shipping box, on the right side panel and on the
rating plate which is located in upper part of draft
hood seen by removing front panel (See "X" Fig. 2,
page 6). Also, each gas orifice is stamped with a
number (78 for LPG and 125 for Natural Gas).
1. Hanging the heater on the wall
a) Drill four pilot holes into the wall, making
sure they are level: 2 at the top and 2 at the
bottom.
The holes should be 21 1/4" apart for the wall
mounting screws which are located in the plas-
tic bag on the side panel of the heater. Use a
1/8 inch drill if screws are to go directly into
studs; otherwise size the holes for the plaster
anchors (also located in plastic bag). Tighten
screws to the wall allowing just enough room
between the wall and the screw heads to allow
for the hanging brackets to slip over them.
b) Attach heat shield cross brace to left and
right hanging brackets with 4 screws. Orient
heat shield with the word " front " facing you.
Hang bracket assembly on 4 screws on the wall.
c) Remove front panel of heater. To do this,
remove front knobs by pulling them off. Un-
screw 3 front panel retaining screws. Pull front
panel up and out. Position the heater over the
hanging bracket metal tabs near the top of the
brackets and then let the heater slip down until
both tabs engage.
2. Connecting the Gas Line
In the United States: The installation must con-
form with local codes or, in the absence of lo-
cal codes, the National Fuel Gas Code ANSI
Z223. 1/NFPA 54.
In Canada: The installation should conform with
CGA B149 INSTALLATION CODES and/or lo-
cal installation codes.
IMPORTANT An appliance gas pressure regu-
lator has been supplied with this unit. This regu-
lator must be installed on the gas line within 6
feet of the heater. National Fuel Gas Code re-
quires that a sediment trap be installed on gas
appliances not so equipped. The 3/4" NPT gas
inlet elbow fitting supplied with the heater con-
nects to the manual gas shutoff valve with a
washer gasket. No pipe dope or thread tape
should be used at this joint. The 3/4" NPT side
of the fitting has a hex shoulder to help you
avoid twisting the elbow and requires pipe dope
or thread tape to make its seal. The 3/4" size
is the minimum for use with Natural Gas and
must not be reduced. Propane gas line size
requirements are less than those for Natural
Gas with some products, but in the case of the
AquaStar 170, the recommended minimum size
is still 3/4", and 7/8" if the length of the tubing
is over 35 feet. See chart, p 27.
