ECHO DIRECT VENT GAS HEATER

Vertical Installation
The maximum vertical distance allowed with this
appliance is 30 feet from the top of the stove to free
atmosphere. Two 45-degree elbows to offset the
vertical
rise are permitted. Clearances to
combustibles when passing through ceilings, walls,
roofs, enclosures, attic rafters, or other close
combustible surfaces are as follows: 1” to pipe
from any combustible surfaces. Vertical rises in
excess of 12’ may require an air restriction
(See
Figure 21).
Notes
1. If an offset is necessary in the attic to avoid
obstructions, it is mandatory to support the vent
pipe every 3 feet, to avoid excess stress on the
elbows (see Figure 6). Vertical installations that
require offsets must use 45-degree elbows. The
45-degree elbows offer less restriction to the
flow of flue gasses and intake air.
2. For multi-story vertical installations, a ceiling
firestop is required at the second floor, and any
subsequent floors.
3. Any occupied areas above the first floor,
including closets and storage spaces that the
vertical vent passes through must be closed.
The enclosure may be framed and sheet rocked
with standard construction materials. Maintain
the clearance to combustibles inside the
enclosure as per the Listing Label. Do not fill
any of the air spaces with insulation.
GENERAL VENTING MAINTENANCE
Conduct an inspection of the venting system semi-
annually. Recommended areas to inspect are as
follows:
1. Check all areas of the venting system exposed to
the elements for corrosion. Corrosion will
appear as rust spots, streaks, and in extreme
cases, holes. Any components with these
symptoms must be replaced.
2. Remove the termination cap and shine a
flashlight down the vent pipe. Remove any bird
nests or other foreign material.
3. Check for evidence of excessive condensation
such as water droplets forming on the inner liner
or dripping from the pipe vent joints.
Continuous condensation can cause corrosion of
caps, pipe, and fittings. It may be caused by
having excessive lateral runs, too many elbows,
and exterior portions of the system being
exposed to cold weather.
4. Inspect joints to ensure that no pipe sections or
fittings have been disturbed or loosened. Check
mechanical supports such as wall straps,
plumbers tape, etc., for strength, fastening, and
rigidity.
Gas Line Installation
Only persons licensed to work with gas piping may
make the necessary gas connection to this
appliance. Be sure gas plumbing instructions and all
provincial and local codes are carefully followed.
Use approved flexible gas connections or rigid
piping, depending on provincial and local codes, to
attach burner to gas supply. Be sure to use proper
size gas supply line. Carefully check all connections
for gas leaks with soap and water solution.
Each installation must conform to all local,
provincial and national codes. Refer to the national
fuel gas code, local zoning and code authorities for
details on installation requirements.
Existing Gas Supply
Before interrupting the existing gas supply it is
recommended that the following be checked.
Shut down all gas appliances and carry out a
pressure test to insure there are no existing leaks on
the system.
