note:
The LV series requires a minimum inside enclosure height, as illustrated (dimension L) measured from the bot-
tom of the appliance. For temperature requirements, this area must be left unobstructed. Some venting con-
fi gurations that require more vertical rise will require a larger enclosure to provide minimum vertical clearance
between vent pipes and combustibles.
