About this file

Written by GovTribe AI · Nov 6, 2025

This document is a USDA Forest Service design and specifications file for the HVAC Replacement project at the Kyle Canyon Bunkhouse located in the Humboldt-Toiyabe National Forest, Spring Mountains National Recreation Area in Nevada. The project involves replacing the existing furnace system, including a 4-ton variable speed propane furnace with 88 MBH input heating capacity and an air-cooled condensing unit with 4 tons cooling capacity and an 18 SEER rating.

Key technical specifications include high-altitude conversion requirements (6,200 feet above sea level), installation of a new condensing unit concrete pad 24" off the roof eave, rerouting coolant lines, adding exterior room venting, and replacing furnace closet walls. The project requires installing refrigeration lines, modifying ductwork, and ensuring compatibility with site conditions. The contractor must use R-454B/R-32 refrigerant and provide 10-year compressor and 5-year parts warranties. The design emphasizes precise installation details, including specific requirements for refrigerant lines, venting, drainage, and electrical connections.
