Remember, no water heating system will provide exact temperatures at all
times.Allow a few days of operation at this setting, to determine the correct
temperature setting consistent with your needs.
Some models have values higher or lower than those noted above. Refer to

(Figure 4).
At least every 3 months a visual inspection should be made of the
venting system.You should look for:
• Obstructions which cause improper venting.
• Damage or deterioration which could cause improper venting or
leakage of combustion products.
