See VII, page 12 for burner input adjustment.
GAS VALVE CONNECTION Size is 13 mm (1/2") f.p.t. for all sizes up to and
including GG-125 and GXH-125 depending upon configuration (natural, L.P.,
standing pilot, IID). Larger boilers, gas valves are 19 mm (3/4").
COMBUSTIBLE FLOOR KIT increases all height dimensions by 51 mm (2").
RAISED SLAB—When mounting boiler on a raised slab, the slab must extend at
least 51 mm (2") beyond the boiler cabinet on all sides.
CHIMNEY HEIGHT: 4.5 m (15 ft.) minimum from draft hood skirt to top of
chimney. CHIMNEY INSIDE DIAMETER must be same as Dimension “C” or
