BOILER SET-UP
A. GENERAL
1. Series PFC
TM
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 Series PFC
TM
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
ure
F
ire
®
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 PFC-625 and PFC-750 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.
2. Remove the leveling legs from the boiler to be
installed on top.
3. The boiler can be lifted several way; with a fork lift, with
a chain hoist using eyebolts through the top mounting
holes of the unit as shown in Figure 2.2, or by passing 5
to 10 foot (2-3 meter) lengths of 1 to 1-1/4” schedule 40
or 80 pipe through the boilers frame.
4. Insert washers and bolts (not provided - See Table
2.1) through the holes provided in the frame of the
lower boiler and holes in the base of the upper boiler.
Figure 2.1 shows this assembly. Tighten the bolts
securely.
5. Replace all the side jacket panels.
