Install Instructions

8
A. GENERAL
1. PUREFIRE
®
boilers are intended for installation in an
area with a floor drain or in a suitable drain pan. Do
not install any boiler where leaks or relief valve
discharge will cause property damage.
2. The P
UREFIRE
®
boiler is not intended to support
external piping. All venting and other piping should
be supported independently of the boiler.
3. Install the boiler level to prevent condensate from
backing up inside the boiler.
4. P
UREFIRE
®
boilers can be wall mounted or floor
standing. The following instructions provide guidance
for both configurations.
B. WALL MOUNTING
1. Models PF-50, PF-80, PF-110 and PF-140:
a. A wall mounting bracket kit (54171) is included
for wall mounting these boiler sizes.
b. Mount the bracket level on the wall using 5/16" lag
bolts. Be sure the lag bolts are fully supported by
wall studs or adequate wall structure.
c. The mounting bracket has (4) holes on 16" centers
as shown in Figure 2.1. This is intended to give
installers the ability to mount the bracket on two
wall studs spaced at this interval. If existing wall
studs are spaced differently or if the desired
location is not in line with the wall studs,
additional support is required.
d. If the boiler is wall mounted using the optional
wall bracket, be sure that the wall provides
adequate support for the boiler.
e. Be sure to adequately support the boiler while
installing external piping or other connections.
f. Be sure that condensate piping is routed to a
suitable drain or condensate pump.
2. All Models can be wall mounted by using the optional
stand (91400).
a. Use the leveling feet provided with the boiler to
assure proper level.
b. Be sure to leave adequate provisions for
condensate piping and/or a pump (if required).
C. FLOOR STANDING INSTALLATION
1. For floor standing installations, use the leveling feet to
assure that the boiler is completely level. This will
prevent condensate from backing up in the boiler.
2. Be sure to leave adequate space for condensate
piping or a pump if required.
BOILER SET-UP
2. BOILER SET-UP
The wall mounting bracket is designed to support the
boiler. External piping for water, venting, air intake
and fuel supply is to be supported separately
WARNING
Figure 2.1: Optional Wall Mounting Bracket for PF-50, PF-80, PF-110 and PF-140 Boilers
This boiler must be installed level to prevent
condensate from backing up inside the boiler.
CAUTION
Make sure the boiler wall bracket is adequately
supported. Do not install this bracket on dry wall
unless adequately supported by wall studs.
