This project proposes to install two new on-demand tank-less water heaters to service the Village Grill.
JUSTIFICATION
Yosemite Hospitality (YH) would like to separate the domestic hot water supplying the visitor restrooms from the supply for the dish washing at the Village Grill. The existing tank water heater cannot meet the demand and does not maintain sufficient temperatures for warewashing. This has become a health department issue, and an action item that YH needs to correct for the CDPH inspections. The machines are not chemically rinsing at the proper temperature on a consistent basis.
SCOPE OF WORK
YH proposes to hang two on-demand tankless water heaters on the Grill exterior in the outdoor employee break area. Exterior installation will allow the units to vent properly while minimizing penetrations to the roof eaves of the historic building. The units would be enclosed in a cabinet with siding and paint to match the building in this area. The frame will be built out of 2 x 4 inch pressure treated wood planks, the siding to be used will be 1 x 6 inch tongue and groove siding to match the existing structure. The door hinges will be stainless steel piano type. The unit will be painted to match the existing structure. Roofing of the cabinet will be composite shingle, matching color and materials with the building roof. The cabinet would measure approximately 5 ½ -feet wide by 7 ¼ -feet tall by 28-inches deep. The depth of the cabinet may be further minimized based on park comments and code compliance. The units would exclusively supply the industrial dish washing equipment in the Village Grill.
These heaters would be connected in series requiring two 1.5-inch penetrations through the wall for ¾" copper pipes and associated insulation. The two lines would be the incoming cold water to be heated and then the high temp water being supplied to the dishwasher. Electrical and propane currently exist on the exterior eve line of the building.
Cabinets will not require punching through for ventilation in the roof or eaves. There is no need for additional screening as this loading dock back-of-house area is screened from public view by an ice bunker, recycling center building, mature deciduous trees, and propane tanks with fenced screening.
