Sample Specifications

MODEL EEDU
ENERGY EFFICIENT, POWER-VENTED INDOOR DUCT FURNACES
Provide 80% thermal-efcient, indoor, gas-red duct heaters as manufactured as Reznor
®
heating equipment.
They shall be designed for a fuel use improvement of 25% through the use of a factory-installed power-venter,
sealed vent product collection chamber, and an intermittent spark-ignited pilot as standard equipment.
Each EEDU Series unit shall be equipped for use with (natural) (propane) gas and (120/1) (208/1) (230/1)
volt power supply. The heat exchanger shall be the Reznor Thermocore
®
design of (aluminized) (E-3 [409]
stainless) steel. Die-formed burners shall be of (aluminized) (E-3 [409] stainless) steel and include ared ports
(burner air shutters) and a stainless steel insert.
These units are to include a 24-volt control transformer, a (single-stage) (two-stage) (two-stage with unit-
mounted ductstat) (two-stage with ductstat with remote temperature selector) (electronic modulation with duct-
stat) (electronic modulation with ductstat and remote set-point adjustment) gas control system with a regulated
combination redundant gas valve, and an intermittent spark pilot with electronic ame supervision (and timed
lockout). The unit is to include all limit and safety controls, including a combustion air pressure switch to verify
proper vent ow before allowing operation of the gas valve.
All units must bear a C.S.A. label. The manufacturer of this equipment must have at least forty (40) years ex-
perience with gas-red duct furnaces.
MODEL SC
SEPARATED COMBUSTION, INDOOR DUCT FURNACES
Provide 80% thermal-efcient, separated combustion, gas-red duct furnaces as manufactured as Reznor
®
heating equipment. They are to be designed for a fuel use improvement of 25% and engineered for use in build-
ing areas with negative pressure and/or extremely dirty or mildly corrosive atmospheres. The use of a factory-
installed power venter to draw combustion air from outside is to prevent dirt, lint, dust, or other contaminants
present in the heated space from entering the unit. The combustion air supply pipe and ue exhaust pipe shall
be run in parallel to a factory-supplied (horizontal) (vertical) vent terminal assembly. The vent terminal/combus-
tion air inlet assembly shall be arranged to allow a single wall or roof penetration.
Each SC Series unit shall be equipped for use with (natural) (propane) gas and (120/1) (208/1) (480/1) volt
power supply. The heat exchanger shall be the Reznor Thermocore
®
design of (aluminized) (E-3 [409] stain-
less) steel and include ared ports (burner air shutters) and a stainless steel insert.
The SC Series shall be provided with 24-volt control transformer, a(n) (single-stage) (two-stage with unit-
mounted ductstat) (two-stage with ductstat with remote temperature selector) (electronic modulation - 50%-
100% ring rate with ductstat) (electronic modulation - 50%-100% ring rate with ductstat and remote set-point
adjustment) (electronic modulation - 50%-100% ring rate, with conditioner for connection to eld-supplied
computer) (electronic modulation - 20/28%-100% ring rate) (electronic modulation - 20/28%-100% ring rate
with conditioner for connection to eld-supplied computer) gas control system with a regulated combination
redundant gas valve and an intermittent spark pilot with electronic ame supervision (and timed lockout). The
SC is to include all limit and safety controls, including a combustion air pressure differential switch to verify
proper vent ow before allowing operation of the gas valve.
All gas-red unit heaters must bear a C.S.A. label. The manufacturer must have a minimum of forty (40) years
experience with separated combustion heating.
MODEL X
INDOOR, GRAVITY-VENTED DUCT FURNACES
Provide 80% thermal-efcient, gas-red, indoor, gravity-vented duct furnaces as Reznor
®
heating equipment.
Model X Series shall be equipped for use with (natural) (propane) gas and (120/1) 208/1) (460/1) voltage/
phase power supply. The heat exchanger shall be the Reznor Thermocore
®
design of (aluminized) (E-3 [409]
stainless) steel with (aluminized) (E-3 [409] stainless) steel drip pan. Die-formed burners shall be constructed
of (aluminized) (E-3 [409] stainless) steel and include ared ports (burner air shutters) and a stainless steel
insert.
The unit is to include a 24-volt control transformer, a(n) (single-stage) (two-stage) (two-stage with unit-mount-
ed ductstat) ( two-stage with ductstat with remote temperature selector) (electronic modulation) (electronic
modulation with ductstat) (electronic modulation with ductstat and remote set-point) gas control system with
a regulated combustion redundant gas valve and a (intermittent spark pilot with electronic ame supervision)
(intermittent spark pilot with electronic ame supervision and timed lockout). The unit is to include all required
limit and safety controls, including a blocked vent shut-off system.
All units must bear a C.S.A. label. The manufacturer of this equipment must have at least forty (40) years ex-
perience with gas-red duct furnaces.
