There is no '42 amp version' of the CH system. The install ratings are in watts but the coil is the same (with 3 sets of taps) for all kits.
The highest wattage install is 5000 watts and uses 21amps at 240vac. It also requires more heat vents and larger duct work than most single propane furnace RVs have. Trying to push that many BTUs into under sized duct work will result in too high discharge air temps and the unit will shut down on thermal limits. The 3700 watt coil is more often used for retrofit installations where its tied to a 30k btu propane furnace.
