Suspended infrared tube heater

The Dayton 7D837 is a suspended infrared tube heater that runs on natural gas and delivers 50000 BtuH of heat output. It is intended for commercial or industrial spaces where radiant warmth is preferred over forced-air systems.

Radiant tube length and coverage

The unit uses a 20 ft radiant pipe to create a floor coverage area of 20 ft x 20 ft at the minimum mounting height. No thermostat is included, so a separate control must be sourced to regulate temperature.

120 V AC hot-surface ignition

Installation requires a 120 V AC supply at 60 Hz and a 4.8 A circuit for the hot-surface ignition system. The heater measures 8 1/2 in high, 18 1/8 in wide and 21 5/8 ft deep, so overhead clearance and gas-line routing must be verified before mounting.

Questions about this item

How often does the hot-surface igniter need replacement on the 7D837?

The hot-surface igniter typically lasts several heating seasons; replacement is only needed if it fails to glow or the heater will not light.

What limits continuous operation of the 50 000 BtuH tube heater?

The 20 ft radiant tube and 0.48 thm/hr fuel rate set the practical output ceiling; the unit runs until the thermostat satisfies or the gas supply ends.

How much noise and heat does the 120 V 4.8 A blower produce all day?

The blower draws 4.8 A at 120 V and runs quietly; radiant heat warms objects directly so ambient air temperature rise stays modest.
