ECHO
DIRECT VENT GAS HEATER
12
Door and Logs
Always allow the heater to cool before carrying out
any maintenance or cleaning. The viewing door
should be opened for service only (see Maintenance
section). Do not place anything inside the firebox
area except authorized Thelin Hearth Products
factory log set. If the logs become damaged, replace
with factory-authorized logs. Never remove,
replace, modify, or substitute any part of this
appliance unless given instructions to do so by
factory-trained personnel or professionally licensed
and certified gas technicians.
Electrical Considerations
WARNING: Electrical Grounding Instructions
.
This appliance is equipped with a three-pronged
(grounding) plug for your protection against shock
hazard and should be plugged directly into a
properly-grounded three-prong receptacle. Do not
cut or remove the grounding prong from this plug.
This must be grounded in accordance with local
codes, or, in the absence of local codes, with the
National Electric Code ANSI/NFPA 70 (in Canada,
Canadian Electrical Code CSA C 22.1).
Safety Check Conclusion
Do not throw this Owner’s Manual away.
This
manual contains important hook-up, operation, and
maintenance instructions. Thelin Hearth Products
grants no warranty, implied or stated, for the
installation and maintenance of your heater and
assumes no responsibility of any consequential
damages as a result of improper installation or
failure to perform routine maintenance.
CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
servicing.
SPECIFICATIONS
Listing Criteria, Lab Accreditation
See Listing Label (See Important Instructions
section) for laboratory listing criteria. When
pressure testing the gas supply at test pressures in
excess of 1/2 psig (3.5kPa) isolate the heater from
the supply line by disconnecting or utilizing the gas
shut off valve.
Manifold Pressure
The heater has a manifold pressure tap (1/8 N.P.T.
fitting) directly on the manifold, (see Figure 21) to
check the manifold pressure downstream of the gas
valve. If the manifold pressure does not match the
following pressure, check inlet pressure and correct
the problem:
Natural gas: High - 3.5” WC, Low – 1.1” WC
Propane:
High – 11.0” WC, Low – 3.8” WC
Orifice Size
The orifices are factory installed for altitudes up to
4,500 feet. If installing in a higher altitude check the
orifice information (see Laboratory Listing Label).
Gas Data
Input BTU:
Natural gas: 27,000 Btu
Propane:
26,000 Btu
Minimum Inlet Pressure:
Natural gas: 4.5” WC (Water Column)
Propane:
11.5” WC
Suggested Maximum Pressure:
Natural gas: 7” WC
Propane:
13” WC
