Modine Fan Time Delay Relay #5H071675 for Modine PDP, BTP, PV, BV, and DFG unit heater models. This time relay delays the start and the stop time for the exhaust fan motor and the room blower fan.

NOTE: There are many specific gas heaters in the market, sometimes called garage, shop, or unit heaters.
Most use a fan time delay to control the PRE-PURGE sequence and COOLING DOWN time.
The timing for ON & OFF varies from 1 to 110 sec.
Those timers differ from regular electric heat sequencers (even though they look alike).

You may find some inexperienced sellers who offers a cheap electric heat sequencer for use in your gas heater as a delay timer - not very smart...

Fan time relays have a particular timing, they are made in relative small quantities for a certain brand/model and cost naturally a bit more.
