FUTERA II INSTALLATION AND OPERATION INSTRUCTIONS
RATINGS & CAPACITIES
Before undertaking the installation of the Futera II 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 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.
NOTE: Service clearances are not mandatory, but are
recommended to ensure ease of service should it be
required.
Table 1

Front 8
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 II 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 2, 3, 4, 5 & 6.
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!
All joints in metal intake air systems must be secured using
corrosion resistant fasteners and sealed using a suitable
Silicone caulk. If PVC or CPVC is used, the joints must be
cleaned with a suitable solvent and connected using a
solvent based PVC cement. The combustion air system
MUST be supported by the building structure not the
boiler/water heater.
CAUTION: A combustion air damper interlocked with
the unit should be installed in the intake air pipe when
the infiltration of subfreezing air could occur, otherwise
the unit could freeze up voiding the warranty!

GENERAL VENTING GUIDELINES
WARNING: The vent installation must be in
accordance with Part 7, Venting of Equipment, of
the National Fuel Gas Code, ANSI Z223.1/NFPA 54latest revision or applicable provisions of the local
building codes. Canadian installations must
comply with CAN/CGA B149.1 or .2 Installation
Code. Improper venting can result in excessive
levels of carbon monoxide which can result in
severe personal injury or death!
All vent systems must be fully supported by the building
structure and not by the boiler/water heater. Appropriate
thimbles and fire-stops must be used where required.
WARNING: Common vent systems must be
properly engineered and sized to provide a
negative draft of 0.01 to 0.08 in,
at the flue outlet. Common positive pressure vent
systems are not to be used. Improper installation
can result in excessive levels of carbon monoxide,
which can cause severe personal injury or death!
NOTE: A single acting

the combined output of all of the appliances.
WARNING: If an appliance using any type of a
mechanical draft system operating under positive
pressure is connected to a chimney flue, never
connect any other appliances to this flue. Doing
so can result in excessive levels of carbon
monoxide which can cause severe personal injury
or death!
Chimney Inspection & Sizing
A thorough inspection of the masonry chimney must be
performed to ensure that the chimney is clean, properly
constructed and properly sized. Exterior masonry chimneys
.
should not be used unless properly lined to prevent
condensation and draft problems. Table 3A lists the
equivalent breeching and flue sizes required for the boiler/
water heater.

1250, 1500 12
1750, 1950 14
Note: These sizes are based on a 20 ft,
Vent Connections
Locate the boiler/water heater as close to the chimney as
possible. Use the shortest, straightest vent connector
possible for the installation. If horizontal runs exceed 5 ft,
1.5 m
they must be supported at 3 ft,
overhead hangers. Use a type B, single wall stainless or
single wall galvanized steel vent pipe the same diameter
as the flue collar to connect the boiler/water heater to a
masonry chimney, see Figure 2. When using a listed metal
chimney system use the appropriate vent connector.

FUTERA II INSTALLATION AND OPERATION INSTRUCTIONS
The vent connector should be sloped up toward the
chimney at a minimum rate of 1/4 in/ft,
21 mm/m
. On
masonry chimneys the connector must terminate flush with
the inside of the chimney flue, Figure 9. Fasten each single
wall vent connection with at least 3 corrosion resistant
sheet metal screws.
Always provide a minimum clearance of 6 in,
152 mm
between single wall vent pipe and any combustible
materials. Type B1 vent may be used, clearance between
it and any combustible material must be as listed.

COMMON VENT SYSTEMS
If an existing boiler/water heater is removed from a
common venting system, the common venting system may
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.
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.
