BOILER SET-UP
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. Many jacket panels on the P
UREFIRE
®
boiler are
removable to allow inspection and maintenance. Do
not attached fixed brackets for piping or wiring on
removable jacket parts. Piping and/or wiring should
not obstruct access to removable panels.
4. Install the boiler level to prevent condensate from
backing up inside the boiler.
5. Use leveling feet to assure that the boiler is completely
level. This will prevent condensate from collecting in
the boiler and causing degradation of the heat
exchanger.
B. STACKING MULTIPLE BOILERS
Identical PF-850 and PF-1000 boilers can be stacked to
save floor space on the installation. Figure 2.1 shows how
the upper boiler is to be attached to the lower boiler.
1. Remove all side jacket panels from the both boilers
and the top jacket panels from the lower boiler.
2. Remove the leveling legs from the boiler to be
installed on top.
3. Lift the upper boiler into place by passing 5 to 10 foot
(2-3 meter) lengths of 1" to 1-1/4" Schedule 40 or 80
steel pipe through the holes provided in the boiler
frame.
4. Insert spacers, washers and bolts (provided) through
the holes provided in the frame of the lower boiler
and thread them into the threaded inserts on the base
of the upper boiler. Figure 2.1 shows this assembly.
Tighten the bolts securely.
5. Replace all the side jacket panels and discard the top
jacket panels from the lower boiler.

Figure 2.1: Stacking and Securing Boilers
This boiler must be installed level to prevent
condensate from backing up inside the boiler.
CAUTION
Do not lift these boilers by hand. Failure to comply
may result in serious injury, death or major property
damage.
