• Failure to follow the instructions provided may result
in personal injury, death or substantial property
damage.
• Any modifications to the boiler, water tank, gas and
water connections, or wiring may void warranty.
• Consult the factory or local factory representative
with any questions or problems regarding this
equipment.
AVERTISSEMENT
Ce manuel donne des renseignements sur
l’application, l’installation et le fonctionnement du
chauffe-eau indirect. Un manuel complet d’instruction
sur le fonctionnement de la chaudière hydronique
(Document 1025) est fourni avec ce manuel. Les deux
manuels doivent être examinés attentivement avant
de procéder à l’installation.
• Si les instructions ne sont pas suivies, il peut en
résulter des blessures personnelles, la mort ou des
dégâts matériels substantiels.
• Toute modification apportée à la chaudière, au
réservoir d’eau, aux branchements de gaz et d’eau
ou aux fils électriques peut invalider la garantie.
• Consultez le représentant de l’usine principale ou
locale pour toute question ou problème concernant
ce matériel.
1.1 Hazards and Your Safety
- Hot Water Can Scald!
The Consumer Product Safety Commission (CPSC)
and some states/provinces recommend a temperature
setting of 130°F (54°C) or less. The water heater
thermostat is factory set to approximately 120°F (49°C).
If thermostat will be set above factory setting, install an
anti-scald valve at either the water heater or at each hot
water faucet.
•
Tempering valves are not anti-scald valves since
they do not have a positive shutoff in case cold
water supply fails. They are not recommended for
shower/tub service. If needed, install an anti-scald
valve at each shower/tub.
• Water heated to a temperature suitable for clothes
washing, dish washing and other sanitizing needs
can scald and cause permanent injury.
• Children and elderly, infirmed, or physically
handicapped persons are more likely to be injured
by hot water. Never leave them unattended in a
bathtub or shower. Never allow small children to
use a hot water tap or draw their own bath. If
anyone using hot water in the building fits this
description, or if state/province laws or local codes
require certain water temperature at hot water taps,
take special precautions:
Install an anti-scald valve at water heater or at each
hot water faucet, bath, and shower outlet.
Use lowest practical temperature setting.
• Studies have indicated that dangerous bacteria can
form in potable water distribution system if certain
minimum water temperatures are not maintained.
Contact local health department for more
information.
SECTION 2.
Installation
This installation must conform with the instructions
in this manual and, where applicable:
National Fuel Gas Code (ANSI Z223.1).
National Electric Code (NEC-NFPA 70).
Local, state, provincial, and national codes, laws,
regulations and ordinances.
In Canada - Natural Gas and Propane Installation
Code, CSA B149.1 and the Canadian Electric Code
(CEC - Can/CSA C22.1.
Where the recommendations made in this manual
differ from local or national codes, the local or national
codes take precedence.
2.1 Location
This water heater/boiler unit is not intended for
outdoor installation. Select a convenient location where
water leakage from the tank or connections will not result
in damage to areas adjacent to the appliance or to lower
floors of the structure. When a safe location cannot be
found, install a suitable drain pan under the appliance,
and pipe it to an adequate drain.
2.2 Heater Placement
The heater must be placed to provide clearances on
all sides for maintenance and inspection. Allow 4 inches
(102mm) on each side for piping access. There must also
be minimum distances maintained from combustible
surfaces. Figure 2 shows minimum clearance from
combustible surfaces. The Mini-Combo unit can be
installed in a closet, as long as the minimum clearances
are maintained. Special attention should be paid to the air
supply opening to the closet. Refer to Table 1.
