1. GENERAL INFORMATION

1.1 FUNCTION

The RS Chimney Fan is a chimney top mounted ventilator
that is designed to provide large flue gas volume capacities.
It is designed and intended for use with residential gas or oil
fired central space heating systems, for volume water heating
or for combination space heating/volume water heating. It is
also suitable for use with gas-fired fireplaces, stoves, BBQ’s
or residential pizza ovens.

This product is developed to prevent draft problems from
occurring by creating a mechanical draft in venting systems
and thereby also increasing the capacity and efficiency of a
venting system.

The use of the RS Chimney Fan is not restricted to any type
of chimney, because the fan creates a negative pressure
(below atmospheric) in the chimney or vent.

Code Compliance

Installations must conform to requirements of the authority
having jurisdiction. Where required by the authority having
jurisdiction, the installation must also conform to the
Standard for Draft Equipment and The National Fuel Gas
Code, ANSI Z223.1/NFPA 54.

All electrical wiring must be in accordance with the
requirements of authority having jurisdiction or, in the
absence of such requirements, with the National Electrical
Code, NFPA70.

Listings

The Model RS is tested and listed to UL Standard 378,
Standard for Draft Equipment. The fan is manufactured
at an ISO9001 certified plant and bears the European CE
compliance label.

The chimney fan must be interlocked with the connected
appliance(s) to insure proper combustions and to avoid flue
gas spillage.

1.2 SHIPPING

The packing list (attached to one of the packages) clearly
lists all items in the shipment and each package has a label
showing the contents. Check the list against all materials on
the job site for completeness.

NOTE: All single phase fans are shipped with a capacitor and
junction box connected via conduit. The capacitor is located
INSIDE the junction box. Please do not discard.

1.3 WARRANTY

ENERVEX products are warranted for a period of two (2)
years following the date of invoice. Replacement or repair
will be at ENERVEX’s discretion, provided factory inspection
shows a defect in material or workmanship.

Complete warranty conditions are available from ENERVEX.

2.2 PLANNING AHEAD

Observe proper combustion air requirements.
Provide a firm support system for the chimney fan.
Determine the type of system involved.
Observe proper safety measures are taken

to assure safe use of the wood burning
appliances.

Combustion Air Requirements

Provisions for combustion air must be in accordance with
applicable local codes.

If the heating system is installed in an unconfied space,
adequate air vill be available via normal infiltration.

If the heating system in installed in a confined space, (a space
with a volume less than 50 cubic feet per 1,000 Btu/hr of
input for all fuel burning equipment) or building construction
is unusually tight, adequate air for combustion must be
provided by two openings: one located about 6" below the
ceiling, the other about 6" above the floor. Each opening
must have a minimum free area as follows:

1. One square inch per 4,000 Btu/hr of input when
communicating directly with the outside or through
a vertical duct.

2. One square inch per 2,000 Btu/hr when communication
through horizontal ducts to the outisde.

3. One square inch per 1,000 Btu/hr when ventilation air
is provided by openings in doors, etc. to adjoining spaces
having adequate infiltration.

System type

Direct connect oil or gas appliances (no draft hood) normally
do not require any mechanical draft adjustment. However,
if there are long horizontal breechings and far between
the appliances, it is a good idea to install mechanical vent
dampers, so adjustments of the draft can be easily made.

Draft hood systems could generally speaking have vent
dampers installed. The vent dampers are used to balance
the system and assure that only a minimum of dilution air is
pulled through the draft hoods.

Safety Devices

Local codes usually require installation of safety devices,
when mechanical draft is provided in an oil or gas fueled
system.

Make sure a differential pressure switch (proven draft switch)
is installed to assure that no appliance will fire unless there is
a proven draft.

Adequate fresh air must be provided for
combustions; otherwise improper operation
and inadequate venting of deadly flue gases
may result.

Support system for the chimney fan

Prior to installation of the chimney fan, it must be assured the
chimney can safely carry the weight of the chimney fan.

A steel chimney should be well supported at the roof
penetration point. If the chimney extends more than 20'
above the roof, the chimney and the fan should be secured
by wires attached on the chimney and on the roof at 2 to 3
different points.

Brick chimneys usually do not need any kind of support to
carry the weight of the chimney fan.
