For access to controls, remove screw in center of doors and swing open
The chrome plated hangers included with the straight model EZ
DUZZIT heater have available suspension rings. If the reflector is to be
flat the hangers should be suspended from the top ring. If the reflectors are to
be angled, the hangers should be suspended from the side ring. Using the chain
provided suspend the four hangers from the ceiling ensuring that the radiant
tube will be parallel to the floor, and with strict adherence to the clearances
to combustibles as listed in this manual and the rating plate on the burner.
Suspend the hangers from either the top or side ring on the hanger as desired.
Once the hangers are suspended the radiant tubes can be placed in the hangers
ensuring that the sight glass is pointing down. Ensure that the enlarged end of
the primary tube, with the set screw is at the desired location for the burner.
Fit the primary tube into the enlarged end of the secondary tube. Install the
screw provided through the predrilled hole in the secondary tube and into the
primary tube in order to secure the two tubes together. With the tubes in place,
the reflectors can now be laded into the hangers.
Remove the protective plastic cap from the nozzle of the burner and place the
nozzle end of the burner into the enlarged end of the radiant tube. Tighten the
set screw so as to secure the burner into place.
For installations in the United States this appliance must not be installed
less than 8 ft. above the floor. In Canada it cannot be installed less than 7
ft. from the floor. It must be installed with strict adherence to clearances to
combustibles.
Install thermostat approximately 5'6 above floor and not located in the
direct ray of the heater. Remove the jumper wire on the burner (marked 24 V
thermostat) and using 24 Volt wiring connect from terminals on the burner to the
thermostat. |

| Venting |
|
| All Venting Must Be in Accordance With All Applicable Codes |
|
- 1. All exhaust venting must be minimum of 4 diameter. The maximum
allowable length of exhaust vent pipe is 15 fl. For every 90 degree elbow in the
vent system, 5 fl. must be deducted from that maximum. Horizontal venting must
be installed with a 1/4 per foot downward slope. The exhaust vent terminal
must be installed not less than 7 fl. above grade.
- 2. The maximum allowable length of fresh air inlet venting is 15 ft. For
every 90-degree elbow in the system, 5 It. must be deducted from that total.
Fresh air seamless air intake duct and screened wall-caps are available from
your Easy Radiant Works supplier. When installed in a building with a negative air
condition, combustion air from outside the negative area is mandatory.

|
| Combustion air Venting |
| When located in a building with a negative air condition or in a dusty or
dirty atmosphere such as a woodworking shop, poultry barn or foundry, venting of
combustion air to the burner from outside the negative or dirty area is
mandatory. The combustion air supply should be minimum 4-inch diameter seamless
air duct, connected to fresh air adapter provided on the combustion air blower.
All joints or seams shall be sealed to prevent leakage. The maximum length of
combustion air inlet shall comply with the venting of products of
combustion as described in this manual.
|
|
| Maintenance |
| Turn off gas and power to burner prior to any servicing. Check for
restrictions in combustion air inlet and exhaust vents prior to each heating
season and periodically during the heating season. The blower motor does not

Heat, Glorious Heat
My system was delivered in two boxes. The heater must be installed at least
7'-0 from the floor with a minimum clearance of 4 from the top of
the reflector to the ceiling. Using the directions and the hardware provided, I
had the system hanging within 30 minutes.
I installed the fresh-air intake hose and the thermostat but had a contractor
(booked ahead of time to coordinate a hook-up date) prepare the exhaust vent and
gas line. Once the Propane Company delivered and hooked up the tank, and
inspected the system, I had heat!
The two-tube, 11 1/2'-0 unit I bought cost $900. It runs from November
to mid- April. My first season cost about $200 in propane; natural gas would be
even cheaper. I tried four different locations for the thermostat, settling at
six feet from the garage door. It's set at 20 deg. Celsius (72 deg. Fahrenheit)
and I leave it at that temperature all the time. Comfy.
