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. 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

ﬂ ow 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 11.

NOTE: Shut off valves and unions should be

installed at the inlet and outlet connections of the

boiler/water heater to provide for isolation of the unit

should servicing be necessary.

Freeze Protection

This boiler/water heater is CSA designed certiﬁ ed for

outdoor installation. Outdoor installations in areas where

the danger of freezing exists are not recommended

unless proper freeze protection is provided. If the unit

is to be installed in such an area the following

precautions MUST be observed:

1. A continuous ﬂ ow of water through the boiler/water

heater MUST be maintained! The pump respon-

sible for ﬂ ow 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 boiler/water heater 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.

CAUTION: Improper outdoor installation of this

boiler/water heater can cause boiler failure voiding

the manufacturer's warranty!

e) Test for spillage at the draft hood relief opening after

5 minutes of main burner operation. Use the ﬂ ame

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 ﬂ amme 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, ﬁ replace dampers

and any other gas-burning appliance to their

previous condition of use.

Une fois qu'il a été déterminé, selon la métode

indiquée cidessus, 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 CSA-B149. Si la grosseur d'une section

du système d'évacuation doit étré modifiée, le

système devrait étré modiﬁ é 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.
