WARNING
By failing to follow the WARNING instructions listed below, a hazardous condition
such as explosion, carbon monoxide poisoning, fire or all of these could result.
• This device is design certified by C.S.A. for use only on
specific Slant/Fin Corporation gas boiler models. These
boilers must also be equipped with a plate or rating plate
which states that the boiler must* (may*) be used with a
Slant/Fin Corp. automatic vent damper device and indicates
the proper vent damper model or part number (See Table 1).
* Boilers under 300,000 Btu/hr. input MUST use a vent damper.
Note: GG-75 HES (Constant circulation),
MAY use a vent
damper.
Boilers with 300,000 Btu/hr. input or greater equipped with IID
(intermittent pilot ignition)
MAY use a vent damper.
Boilers with 300,000 Btu/hr. input equipped with continuous
pilot and VR8300A gas valve MAY use a vent damper.
• This device must be installed and inspected annually by a quali-
fied installer in accordance with the Slant/Fin vent damper
installation instructions, Slant/Fin boiler installation instructions
and the vent damper manufacturer's installation instructions
included with this damper. If improperly installed, a hazardous
condition such as explosion or carbon monoxide poisoning could
result. If installed improperly, all vent damper and boiler war-
ranties shall be voided.
• Use of this device on boilers other than those indicated above is
not permitted.
•
CAUTION: When servicing controls all wires must be labeled
prior to disconnection. Wiring errors can cause improper and
dangerous operation.
• This device must be installed on the outlet end of the draft hood
of the boiler as close to the draft hood as practicable, and with-
out modification of the draft hood (see figures 3 through 7).
• The inlet size of the vent damper must be the same nominal
trade size as the outlet of the draft hood. See Table 1 for the
boiler models and their corresponding vent damper models.
• The device must be located in a venting system or section of a
venting system so that it serves only the single appliance for
which it is installed.
• Clearances of not less than 6 inches (152 mm) must be main-
tained from combustible materials, with provisions for access.
• If the boiler will not fire, DO NOT jump any of the safety controls
(the vent damper circuit is part of the safety control circuit).
