GENERAL
A new feature of the seriesMH12 heaters is a 3-step regulator valve that has a high setting and a low setting. The Infra-Red series
MH12 camp heaters are tested and shipped from the factory assembled, except for the propane gascylinder. The Camp Heaters
will operate approximately – 1 ½ hours on a 14 oz. Cylinder -Disposable
18 ½ hours on No.2011 P.O.L. Cylinder – Refillable
37 hours on No. 2020 P.O.L. Cylinder – Refillable
Above figures are calculatedon the assumption that theheater is turned “Full On” at alltimes. Because it will not be necessary in
many cases to have theheater turned “Full On” at all times, you can count onconsiderably longer burning times for each cylinder.
Cylinders are available in mostsporting goods stores,camping centers and propane outlets.
