Welcome to the forum, some of the members are/were boating people
If anyone has/had that type of heater, then I am sure they will come forward with the info you require
In the meantime Webasco have a website from where you can obtain their phone number, and email address.
They would most probably have that info at their fingertips
And it's welcome from us two 2
As I'm a land lubber not a salty I can not help .
But if no one comes along perhaps posting this question in the tech section might flush out the answer for you.
Happy sailing
Woody
