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.
