RATINGS & CAPACITIES
Before undertaking the installation of the Futera III Series
boiler/water heater check the rating plate to ensure that the
unit has been sized properly for the job. The “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
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.
NOTE: Service clearances are not mandatory, but are
recommended to ensure ease of service should it be
required.
Table 1

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 floor is structurally sound and will
support the weight of the boiler/water heater.
NOTE: The Futera III may be installed directly on
combustible flooring, 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
“GENERAL VENTING GUIDELINES”.

Intake Air Option – General Guidelines
This configuration provides combustion air directly to the
boiler/water heater’s air intake using a dedicated pipe when
using the direct vent option. The RBI air intake adapter
must be fitted to the blower inlet. Combustion air can be
drawn in horizontally through the same outside wall which
terminates the exhaust gases or vertically through the roof,
see Figures 1, 2, 3 & 4.
WARNING: Common intake air systems may be
used provided the common duct is sized properly
and an intake combustion air damper is installed
in the intake air pipe of each heater. Improper
installation can result in excessive levels of carbon
monoxide which can cause severe personal injury
or death!
Single wall galvanized smoke pipe, single wall aluminum
pipe, flexible aluminum pipe, PVC or CPVC pipe can be
used for the intake air pipe. It must be sized per Table 3.
When ducts are used, they must have the same crosssectional area as the free area of the opening to which they
connect.
When calculating the free area necessary to meet the
make-up air requirements of the enclosure, consideration
must be given to the blockage effects of louvers, grills and
screens. Screens must have a minimum mesh size of
1/4 in,
6.4 mm
. If the free area through a louver or grill is
not known, ducts should be sized per Table 2.

then be too large for the proper venting of the remaining
appliances connected to it. At the time of removal of an
existing boiler/water heater, the following steps shall be
followed with each appliance remaining connected to the
common venting system placed in operation, while the
other appliances remaining connected to the common
venting system are not in operation.
Au moment du retrait d’une chaudière existante, les
mesures suivantes doivent être prises pour chaque
appareil toujours raccordé au système d’évacuation
commun et qui fonctionne alors que d’autres appareils
toujours raccordés au système d’évacuation ne fonctionnent pas: système d’évacuation
a) Seal any unused openings in the common venting system.
Sceller toutes les ouvertures non utilisées du système d’évacuation.
b) Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deficiencies
which could cause an unsafe condition.
Inspecter de façon visuelle le système d’évacu-ation
pour déterminer la grosser et l’inclinaison horizontale
qui conviennent et s’assurer que le système est exempt
d’obstruction, d’étranglement de fruite, de corrosion et
autres défaillances qui pourraient présenter des risques.
c) Insofar as is practical, close all building doors and
windows and all doors between the space in which the
appliances remaining connected to the common venting
system are located and other spaces of the building. Turn
on clothes dryers and any appliance not connected to the
common venting system.Turn on any exhaust fans, such
as range hoods and bathroom exhaust, so they will operate
at maximum speed. Do not operate a summer exhaust
fan for a boiler installation. Close fireplace dampers.
Dans la mesure du possible, fermer toutes les portes
et les fenêtres du bâtiment et toutes les portes entre
l’espace où les appareils toujours raccordés du système
d’évacuation sont installés et les autres espaces du
bâtiment. Mettre en marche les sécheuses, tous les
appareils non raccordés au système d’évacuation
commun et tous les ventilateurs d’extraction comme les
hottes de cuisinère et les ventilateurs des salles de bain.
S’assurer que ces ventilateurs fonctionnent à la vitesse
maximale. Ne pas faire fonctionner les ventilateurs
d’été. Fermer les registres des cheminées.

FUTERA III INSTALLATION AND OPERATION INSTRUCTIONS
d) Place in operation the appliance being inspected. Follow
the lighting instructions. Adjust thermostat so appliance
will operate continuously.
Mettre l’appareil inspecté en marche. Suivre les
instructions d’allumage. Régler le thermostat de façon
que l’appareil fonctionne de façon continue.
e) Test for spillage at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a
match or candle, or smoke from a cigarette, cigar or
pipe.
Faire fonctionner le brûleur principal pendant 5 min
ensuite, déterminer si le coupe-tirage déborde à
l’ouverture de décharge. Utiliser la flamme d’une
allunette ou d’une chandelle ou la fumée d’une
cigarette, d’un cigare ou d’une pipe.
f) After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers and
any other gas-burning appliance to their previous
condition of use.
Une fois qu’il a été d éterminé, selon la métode
indiquée ci-dessus, que chaque appareil raccordé au
système d’évacuation est mis à l’air libre de façor
adéquate. Remettre les portes et les fenêtres, les
ventilateurs, les registres de cheminées et les appareils
au gaz à leur position originale.
g) Any improper operation of the common venting system
should be corrected so the installation conforms with
the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
When resizing any portion of the common venting
system, the common venting system should be resized
to approach the minimum size as determined using the
appropriate tables in Appendix F in the National Fuel
Gas Code, ANSI Z223.1/ NFPA 54 and or CAN/CGA
B149 Installation Codes.
Tout mauvais fonctionnement du systéme d’évacu-tion
commun devrait étré corrigé de façor que l’installation
soit conforme au National Fue Gas Code, ANSI
Z223.1/NFPA 54 et (ou) aux codes d’installation CAN/
CGA-B149. Si la grosseur d’une section du système
d’ évacuation doit étré modifiée, le système devrait étré
modifié pour respecter les valeurs minimales des
tableaux pertinents de l’appendice F du National Fuel
Gas Code, ANSI Z223.1/ NFPA 54 et (ou) des codes
d’installation CAN/CGA-B149.
GENERAL PIPING REQUIREMENTS
CAUTION: Improper piping of this boiler/water heater
will void the manufacturer’s warranty and can cause
boiler failure resulting in flooding and extensive
property damage! Excessive water hardness causing
scaling in the copper heat exchanger tubes is NOT
covered under the manufacturer’s warranty, see Table
7. Excessive pitting and erosion of the internal surface
of the copper heat exchanger tubes is NOT covered
under the manufacturer’s warranty if the result of high
water flow rates, see Table 7. Return water
52°C
temperatures below 125˚F,
exchanger damage from excessive condensation
voiding the manufacturer’s warranty, see Primary /
Secondary Piping, Figure 9.
NOTE: Shut off valves and unions should be installed
at the inlet and outlet connections of the boiler/hot
water heater to provide for isolation of the unit should
servicing be necessary.
Freeze Protection
Installations in areas where the danger of freezing exists
are not recommended unless proper freeze protection is
provided. The following precautions MUST be observed:
1. A continuous flow of water through the unit MUST be
maintained! The pump responsible for flow through the
boiler/water heater must run continuously!
2. An ethylene glycol/water mixture suitable for the
minimum temperature that the unit will be exposed to
must be used. The pump must be capable of producing
a minimum of 15% more flow and overcoming a 20%
increase in head loss. Domestic water systems must be
isolated from the water heater by the use of a heat
exchanger or other approved method.
3. If the unit must be shut off for any reason the electric,
gas and water supplies MUST be shut off and the unit
and its pump completely drained.
Relief Valve
Pipe the discharge of the pressure relief valve as shown
in Figure 8.
WARNING: Never install any type of valve between
the boiler/water heater and the relief valve or an
explosion causing extensive property damage,
severe personal injury or death may occur!
Flow Switch
The flow switch supplied with the boiler/water heater must
be wired to the terminal strip in the control panel to prevent
the boiler from firing unless there’s adequate water flow
through the unit. The flow switch must be installed in the
supply piping adjacent to the boiler outlet connection.
will result in heat
CAUTION: Failure to properly install the flow switch
may result in damage to the boiler/water heater heat
exchanger voiding the warranty!
