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
temperatures below 125˚F, 

52

°

C

 will result in heat

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.

CAUTION: Failure to properly install the flow switch
may result in damage to the boiler/water heater heat
exchanger voiding the warranty!
