PART 1. GENERAL INFORMATION
(FIGURE 1-2) APPLIANCES CLEARANCES
(NOTE:
THE APPLIANCE IS RATED AT ZERO
CLEARANCE TO COMBUSTIBLES.)
G. PRE-INSTALLATION REQUIREMENTS
F. DIMENSIONS (continued)
The appliance models 800–1500
are designed to be installed using a
factory designed and supplied rack or
frame. It can be installed in alcoves,
basements, and utility rooms, as
well as standard equipment rooms.
Choose a location for your appliance,
centralized to the piping system,
along with consideration for Electrical
(Part 2, Gas Connection (Part 3),
Venting (Part 4), and Condensate
Drain (Part 4, Section F).
The appliance rack must be level as
installed, and the mounting surface
must be designed to support the
weight (see previous page, Table 1-2
for weights). Be sure the appliance is
adequately secured to the mounting
surface.
The front cover is secured by a Hex
Head Latch.
When removing the
front cover of the appliance, you
must make sure all electric power
to the appliance is turned off
.
If the appliance is set up for use on
liquefied petroleum (LP) gas, some
geographic areas follow the Uniform
Mechanical Code, section 304.6,
“Liquefied petroleum gas burning
appliances shall not be installed in
a pit, basement or similar location
where heavier-than-air gas might
collect. Appliances so fueled shall not
be installed in a below grade under-
floor space or basement
unless
such location is provided with an
approved means for removal of
unburned gas
.”
Note:
A water chemistry analysis
should be performed prior to any
installation. If the water quality
exceeds any of the following levels,
then a water chemistry analysis must
be performed:
• Water hardness can be no more
than 12 grains (205 ppm or mg/l)
• TDS (total dissolved solids) can
be no more than 450 ppm or
mg/l
• PH—below 6.5 or above 7.5
For total combined hardness over
15 grains (250 ppm or mg/l) or
longer pipe lengths, contact the
Manufacturer for correct pump
sizing. Combined, the hardness and
TDS can be no more than 450 ppm.
Our internal term for this is the TCH
(Total Combined Hardness).
