How deep are the water heater pans?
The standard depth for the aluminum and plastic pans is 2½”.
We also offer 3” deep plastic pans in all sizes for those areas where 3” depth is required. 3” deep pans are only available in 18” / 20” / 22” / 24” / 26” / 28” and 30”
Can different drain materials/sizes be used when connecting the drain to the water heater pans?
We offer 3 different fitting adaptors for our pans:
#34086 - 1” inside & 1½” over PVC Adaptor. This adaptor allows you to solvent weld a piece of 1” PVC or a piece of 1½”PVC pipe into the adaptor.
#34088 – 1” inside & 1½” inside PVC Adaptor. This adaptor allows you to solvent weld a piece of 1” PVC pipe into the adaptor, or solvent weld a 1½” PVC fitting hub onto the adaptor.
#34089 - 1” CPVC adaptor. This adaptor allows you to solvent weld a piece of 1”CPVC into the adaptor hub.
If you need further clarification on these installation options, please contact customer service and they can send you an illustrated copy of application instructions.
Can a plastic water heater pan be installed above a finished ceiling?
You should always check with your local building and fire officials before installing a plastic
pan above a finished ceiling. If the return air to the furnace is not isolated through air tight
duct work or the open ceiling is used for the return air, the plastic pan should never be used. If
the plastic pan is used in these applications and exposed to flames, the toxic smoke can be
drawn back to the furnace and distributed throughout the building.
Which water heater pan should be used when installing a water heater?
The plastic pan is not approved for gas water heater installations, and the aluminum pan must
be used. The plastic and aluminum pans are approved for electric water heater installations.
