Airfoil contoured dimpled tubes allow expansion and contraction stresses to flow
out evenly across the heat exchanger tubes. There are no ridges or sharp bends
in the tubes where stresses can concentrate to cause early heat exchanger failure
through metal fatigue. Operational noises during warm-up and cool down are also
minimized by the tube design. Heat exchangers are die formed from corrosion and
rust resistant 20 gauge aluminized steel.
Power Vent System
PDP heaters feature a blower powered vent
exhaust. Power vents force heater exhaust fumes outside of the heated structure,
and allow the heater to be vented vertically or horizontally. Horizontal venting
keeps heat from escaping out of the vent pipe when the heater is not running.
This is especially important when using gas powered heaters in greenhouses. Conventional
vents use natural air drafts (chimney effect) to expel exhaust fumes. Unvented
heaters leave these fumes in the greenhouse which can be harmful to plants.
Corrosion resistant aluminized steel with
slotted, oversized ports and stainless steel separator strip to help prevent clogging
and reduce maintenance.
Aluminized steel with
baked-on gray powder paint finish. Hinged bottom pan allows access to burner and
pilot assembly. Removable side panels enables maintenance and suspension point
115 volt power supply and 25 volt controls. Limit control shuts off main burner
to prevent overheating. Single stage intermittent pilot ignition with safety redundant
gas valve. 100% safety shut-off with continuos retry. Pilot flame is automatically
lit on call for heat.
|J - Diameter of round vent pipe needed to fit oval
|Gas Connections - natural gas may vary depending on
|K - PDP30 - PDP300 have 2 holes (and level hanging
adjustment), PDP350 - PDP400 have 4 holes
|L - Dimension equals overall plus 6".
Clearances to Combustibles
|Do not use PDP units with duct work.
|It is recommended that all gas heaters be installed by a qualified
installation and service contractor.
|Heat Throws are calculated at 65 degrees F ambient and unit
fired at full rated input.
|Ratings shown are for elevations up to 2,000 feet above sea
level. For elevations above 2,000 ft., ratings should be reduced by approximately
4% for each 1,000 ft. above sea level.
