RATINGS & CAPACITIES
Before undertaking the installation of the Futera XLF Series boiler/
water heater check the rating plate to ensure that the unit has been sized
properly for the job. Th e "Net I=B=R Ratings" specify the equivalent
amount of direct cast iron radiation that the unit can supply under normal
conditions. Also ensure that the unit has been set up for the type of
gas available at the installation site. Other important considerations
are the availability of an adequate electrical supply, fresh air for
combustion and a suitable chimney or vent system.

BOILER/WATER HEATER LOCATION

1. This boiler/water heater is suitable for indoor and outdoor
installations. Locate the boiler/water heater in an area
that provides good access to the unit. Servicing may
require the removal of jacket panels. Allow the minimum
clearances between adjacent construction and the boiler/water
heater as listed in Table 1.
Service clearances are not mandatory, but are
recommended to ensure ease of service should it be
required.

2. An optimum site will be level, central to the piping system, close
to a chimney or outside wall and have adequate fresh air for
combustion. Ensure that the boiler/water heater is level from
front to back and from side to side. Use metal shims to level the
boiler/water heater. Electrical and electronic components must
also be protected from exposure to water during operation and
maintenance. DO NOT install this boiler/water heater in a
location that would subject any of the gas ignition components
to direct contact with water or excessive moisture during
operation or servicing.
3. Ensure that the fl oor is structurally sound and will support the
weight of the boiler/water heater.
The Futera XLF may be installed directly on
combustible fl ooring, but never on carpeting.
4. Locate the boiler/water heater in an area that will prevent
water damage to adjacent construction should a leak occur or
during routine maintenance. If such a location doesn't exist, a
suitable drain pan that's adequately drained must be installed
under the unit.
5. DO NOT place this boiler/water heater in a location that
would restrict the introduction of combustion air into the unit
or subject it to a negative pressure, see "GENERA L VENTING
GUIDELINES".

6. NEVER place this boiler/water heater in a location
that would subject it to temperatures at or near freezing,
see the "FREEZE PROTECTION" section on page 14.
Never store combustible materials, gasoline or any
product containing fl ammable vapors or liquids in the
vicinity of the boiler/water heater. Failure to comply
with this warning can result in an explosion or fire
causing extensive property damage, severe personal
injury or death!
COMBUSTION AIR & VENTILATION
This boiler/water heater must be supplied with
combustion air in accordance with Section 5.3, Air
for Combustion & Ventilation, of the latest revision
of the National Fuel Gas Code, ANSI Z223.1/NFPA
54 and all applicable local building codes. Canadian
installations must comply with CAN/ CGA B149.1
or .2 Installation Code for Gas Burning Appliances
and Equipment, or applicable provisions of the
local building codes. Failure to provide adequate
combustion air for this boiler/ water heater can result
in excessive levels of carbon monoxide which can result
in severe personal injury or death!
To operate properly and safely this boiler/water heater requires a
continuous supply of air for combustion. NEVER store objects on
or around the boiler/water heater!
Combustion air contaminated with fluorocarbons
or other halogenated compounds such as cleaning
solvents and refrigerants will result in the formation
of acids in the combustion chamber. Th ese acids will
cause premature failure of the boiler/water heater
voiding the warranty!
If the boiler/water heater is operated while
the building is under construction it MUST be
protected from wood, concrete, sheet rock and other
types of dust. Failure to properly protect the unit from
construction dust will damage the unit voiding the
warranty!
Buildings will require the installation of a fresh air duct or
other means of providing make-up air if the intake air option
isn't used. Any building utilizing other gas burning appliances, a
fi replace, wood stove or any type of exhaust fan must be checked for
adequate combustion air when all of these devices are in operation
at one time.
Sizing of an outside air duct must be done to meet the requirements
of all such devices.
Never operate the Futera XLF in an environment
subjected to a negative pressure unless it is Direct
Vented. Failure to comply with this warning can result
in excessive levels of carbon monoxide causing severe
personal injury or death!
