Additional Information About Our Heaters
|
Single Stage Thermostat
Southern Burner heaters are equipped with millivolt controls
and wall mounted thermostat that require no electricity for operation. Two styles
are available: The first being a Single Stage Thermostat that has a temperature
range of 35 to 75 degrees. When you select a temperature setting the heater will
cycle on and off at this setting. Regardless of the time of day or night.
|
Set Back Thermostat
The Second Style is a Day and Night Set-Back Thermostat. This gives you the capability
of two separate temperatures, one for day and one for night. The thermostat has
an adjustable clock that you can choose from 15 minute intervals to set the temperature
change from day to night settings. The clock is powered by an "AA" Alkaline battery
still giving you the convenience of no electricity. Temperature range is from 45
to 90 degrees. Mounting of the thermostat can be up to 25 feet from the heater and
should be shielded form direct sunlight or water.

Safety
All controls have a 100% safety cut-off feature. If the pilot flame should go out
for any reason, the millivolt control would shut off all gas to the heater. Pilot
flame would have to be re-established before heater would operate.

Natural and L.P. Gas
Southern Burner heaters are designed to operate under the side benches, installed
flush with the front edge of the growing bench or at the end of the isle. Heaters
are available for natural or L.P. gas. Heaters on L.P. gas must have a regulator
on L.P. tank.

Heating Capacity
In Northern states, it is suggested that one unit be placed for every 150 to 175
square feet of floor space in a conventional greenhouse. In Central states, place
on unit heater to every 200 square feet of floor space. In the Southern states,
we allow as much as 225 square feet to one unit.

Proper Ventilation
Do not over look the necessity of providing a way for fresh air to enter the greenhouse.
This is a 'must' and should not be eliminated. Illustrations show the proper way
to install the air intake pipe for the model (C-1) and the model (A-1). A slight
top ventilation is also necessary in the greenhouse to provide for circulation and
exhaust. In case of heavy snows, take care not to let the vent pipe get buried as
the heaters as the heaters need oxygen to burn properly.
