INSTALLATION PLANNING (cont.)
The following tables are provided to assist the licensed electrician in sizing the electric cables and/or plugs
needed for each FHK heater model. Since only models FHK-212-1CA and FHK-624-1CA are equipped with
cables and plugs, these items for all other models will have to be obtained through a local supplier or purchased
separately from Fostoria. (See Table B.)
All supply cables must be copper, rated 90°C and comply with all local codes and the National Electric Code
(NEC).
All recommended wire sizes assume a 50ft. maximum wire length.
