GlobalTowne is an Authorized Marey Distributor and we carry the full line of Marey Gas tankless water heaters. The Marey GA16L, GA10L and the GA5L units all ignite using a battery ignition. The units require 2 - D cell batteries to operate the ignition and with the units with the digital panel will use a little more as these show the temperature while the unit is running.
The longevity of the D cell batteries will all depend on the usage. The batteries are only used for the ignition spark and for the digital display. Under normal household usage the batteries should be changed every 6 months or so. Below is a list of the Marey gas tankless water heaters that require the battery ignition.
