INSTALLATION
!
WARNING
Improper installation, adjustment, alteration, service
or maintenance could result in death or serious
injury.
Installation
Installation shall conform to requirements of authority
having jurisdiction or in the absence of such requirements,
NFPA 31: Installation Code for Oil Burning Equipment.
Where required by authority having jurisdiction, installation
shall conform to standard for Controls and Safety Devices
for Automatically fi red boilers, ANSI/ASME CSD-1.
Locate boiler in front of fi nal position before removing
crate. Provide level solid base as near to vent outlet
as possible and centrally located with respect to heat
distribution system as practical.
Allow 24 inches in front and top for servicing and cleaning,
or removing tankless water heating coil.
Fire hazard. Do not install boiler on combustible fl ooring
or carpeting. Failure to follow these instructions could
result in death or serious injury.
FOR INSTALLATION ON NON-COMBUSTIBLE FLOORS ONLY
- The boiler must not be installed on carpeting or vinyl
fl ooring. Minimum clearances to combustible construction
are:
Minimum clearances to combustible construction are:
TOP .................................................0 IN.
FRONT .... ......................................24 IN.*
FLUE CONNECTOR .............................2 IN.
REAR ...............................................6 IN.
LEFT SIDE ........................................0 IN.
RIGHT SIDE ......................................0 IN.
Recommended clearance for service access should exceed
fi re protection clearance.
!
WARNING
* "FOR ALCOVE INSTALLATION"
When installed in utility room, door should be wide enough
to allow largest boiler part to enter, or permit replacement
of another appliance such as water heater.
TOP ...............................................24 IN.
FRONT ...........................................24 IN.
FLUE CONNECTOR .............................9 IN.
REAR ...............................................6 IN.
LEFT SIDE ......................................10 IN.
RIGHT SIDE ......................................6 IN.
Remove crate and plastic protective wrapper and inspect
for damage.
Our responsibility ceases upon delivery of the crated boiler

CONNECTING SUPPLY AND RETURN PIPING
Circulators in following illustrations are mounted on
system supply side, mounting on system return side is also
acceptable practice.

Hot water boilers installed above radiation level must
be provided with low water device either as part of
boiler or at time of boiler installation.
Figure
Figure
• Method used to protect systems using radiant
panels and material they are encased in from high
temperature supply water from boiler. See
3
.
• Method used to protect boilers from condensate
forming due to low temperature return water.
Generally noticed in large converted gravity systems
or other large water volume systems. See
Figure
Figure 4
.
4.
When boiler is connected to heating system utilizing
multiple zoned circulators, each circulator must be
supplied with fl ow control valve to prevent gravity
circulation.
• Reduced pressure back fl ow preventer must be
present under provisions required by Environmental
Protection Agency (EPA).
5.
Bypass piping is an option which gives ability to adjust
supply boiler water temperature to fi t system or
condition of installation. This method of piping is not
typically required for baseboard heating systems.
Figure 3
• Method used to protect boilers from condensate
forming as well as protecting heating system from
high water temperature. See
6.
When using bypass piping, adjust valves A and B until
desired system temperature is obtained.
7.
Bypass loop piping must be same size piping for supply
and return.
8.
Connect supply and return piping as suggested in
Figure 6
refrigerated systems:
