GASLAND CE686LP 199,000 BTU Propane Tankless Water Heater

What it delivers

The GASLAND CE686LP 199,000 BTU Propane Tankless Water Heater is a propane tankless with a 199,000 BTU/h burner and a stated maximum flow of 7.6 GPM. Its listing gives a UEF of 0.8.

Flow depends on how cold the incoming water is. Our estimate from its input: 6.8 GPM at a 45°F rise, falling to 4.4 GPM at 70°F, which is 2 showers at 2 GPM on a cold-climate winter day. Check it against your own fixtures.

The line must deliver about 2.2 gallons of propane an hour when it fires flat out. The requirement calculator adds it up; a licensed fitter confirms the pipe.

Its exhaust runs hot, so the vent must be the material its manual lists, usually stainless; budget for the vent kit.

Also on the listing: material: Iron, copper; model: CE686LP.

The listing gives dimensions of 14.25 in (W) x 24.69 in (H) and a weight of 37.5 lb.

From its 199,000 BTU/h input we estimate about 6.8 GPM at a 45°F rise and 4.4 GPM at a 70°F rise, so 3 two-GPM showers with mild inlet water and 2 in a cold winter. The maker's flow chart for this model is the final word.

What size gas line does the GASLAND CE686LP 199,000 BTU Propane Tankless Water Heater need?

At full fire it uses about 192 cubic feet of natural gas an hour or 2.2 gallons of propane. The pipe size depends on the length of the run and every other gas appliance on it; the maker's manual and a licensed gas fitter decide it.
